Lukas Hörmann has successfully competed for a UFO postdoctoral fellowship from the Austrian state of Styria. The project has a duration of one year and is entitled "Switchable superlubricity". Superlubricity, a state of ultra-low friction, will facilitates a significant reduction of friction-related energy loss and device failure of any moving mechanical device. Given the trend towards miniaturisation of such devices, studies of mechanical properties at atomic scales become ever more important. Developing nanoscale devices exhibiting superlubricity requires a detailed understanding of the fundamental principles governing dynamic sliding friction at an atomic scale.

Sandro Wieser received a DOC fellowship
Sandro Wiesner won a fellowship from the Austrian Academy of Sciences entitled “Understanding heat transport in metal-organic frameworks in real and reciprocal space”. The high inner surface area of Metal-organic frameworks (MOFs) is utilized in a large range of applications including gas separation, gas storage or catalysis. Many of the involved processes generate or consume heat. Efficient heat dissipation is often essential to maintain stable and efficient working conditions. Therefore, it is important to investigate heat transport in MOFs. Due to the enormous number of different MOFs, it is crucial to not only provide thermal conductivity values for specific systems, but to fundamentally understand structure-to-property-relationships for heat transport. To achieve this, several complementary theoretical techniques will be applied to analyze thermal transport for different MOFs. Molecular dynamics simulations will show locally resolved transport bottlenecks in real space, while the phonon picture will provide understanding regarding the origin of different heat transport properties in reciprocal space. This will pave the way for a targeted tailoring of MOFs for specific applications relying on heat transport via structural modifications.

Tunneling Probability Increases with Distance in Junctions Comprising Self-assembled Monolayers of Oligothiophenes
Molecular tunneling junctions should enable the tailoring of charge-transport at the quantum level through synthetic chemistry but are hindered by the dominance of the electrodes. We show that the frontier orbitals of molecules can be decoupled from the electrodes, preserving their relative energies in self-assembled monolayers even when a top-contact is applied. This decoupling leads to the remarkable observation of tunneling probabilities that increase with distance in a series of oligothiophenes, which we explain using a two-barrier tunneling model. This model is generalizable to any conjugated oligomers for which the frontier orbital gap can be determined and predicts that the molecular orbitals that dominate tunneling charge-transport can be positioned via molecular design rather than by domination of Fermi-level pinning arising from strong hybridization. The ability to preserve the electronic structure of molecules in tunneling junctions facilitates the application of well-established synthetic design rules to tailor the properties of molecular-electronic devices.
This work is a collaboration between the Stratingh Institute for Chemistry and the Zernike Institute for Advanced Materials, University of Groningen (Netherlands) with the Institute of Solid State Physics, TU Graz.
Embedded-dipole self-assembled monolayers tune contact resistances in p‐type and n‐type organic transistors
Highly conductive interfacial layers are designed, which allow tuning the contact resistance of organic thin‐film transistors over three orders of magnitude with minimum values well below 1 kΩ cm. This not only permits the realization of highly competitive p‐type (pentacene‐based) devices on rigid as well as flexible substrates, but also enables the realization of n‐type (C60‐based) transistors with comparable characteristics utilizing the same electrode material (Au). The contact resistances are reduced by i) eliminating the injection barrier through a suitable dipole orientation, and by ii) boosting the transmission of charge carriers through a deliberate reduction of the SAM thickness. Notably, the embedding of the dipolar group into the backbones of the SAM‐forming molecules allows exploiting their beneficial effects without modifying the growth of the active layer.
This work is a collaboration between the Institute of Solid State Physics, TU Graz, the Stadlober group at the Materials Institute, Joanneum Research, Weiz (Austria), the Zharnikov group at the University of Heidelberg (Germany), and the Terfort group at the Goethe University Frankfurt/Main (Germany).

Such transistors represent an increasingly important technology, since they can be cheaply fabricated on large and flexible substrates. To date, however, their operating speed cannot compete with the switching speed of silicon-based transistors. Theoretical simulations will employed to demonstrate that the apparent lack of switching speed is due to an inefficient injection of charge carriers from the electrodes.

Planet Research: Small - Smaller - Molecular Electronics >> more >>
Electronic objects of daily life are becoming increasingly smaller – but at the same time more powerful and efficient. The research area of molecular electronics, a sub-area of microelectronics, aims at miniaturisation, and research in this field is being carried out at the Institute of Solid State Physics at TU Graz. At the centre of interest is how electricity can flow in individual molecules, molecular layers (i.e. in a layer of arranged molecules) and in molecular clusters. “Molecular electronics is the ultimate miniaturisation of electronics – single molecules suddenly become active elements and circuits become considerably smaller than they are, for instance, in microelectronics,” explains Egbert Zojer from TU Graz’s Institute of Solid State Physics.
June has been a very successful month for Oliver Hofmann and his group, with three papers accepted in peer-reviewed journals.

The aim of Anna Maria Coclite’s ERC-sponsored project “Smart Core” is to develop a hybrid material which can perceive temperature, humidity and pressure simultaneously and react accordingly. State-of-the-art materials currently include three different sensors for the perception and transmission of individual stimuli. The three-in-one hybrid material which Coclite and her team will work on simplifies the sensors of artificial skin and can increase sensory resolution 20-fold in comparison to human skin. This hugely increased sensory resolution of the novel hybrid material is achieved using a variety of nanorods on a surface. The “smart core” of these nanorods, hence the name of the project, consists of a polymer which responds to temperature and humidity by expanding. The change in thickness of the polymer exerts pressure on its shell, i.e. the nanorods, and these react sensitively to the pressure and in turn trigger stimuli. The hybrid material will achieve some 2,000 sensors per square millimetre, and thus spatial resolutions far below one millimetre, which corresponds to that of the human fingertip.
Anna Maria Coclite won the IAAM Scientist Medal 2016, awarded by the International Association of Advanced Materials for her “notable and outstanding research in the Advanced Materials Science and Technology” (as written in the certificate).

Oliver T. Hofmann was granted a three-year stand-alone project by the Austrian Science Fund FWF to study “Defects at Inorganic/Organic Interfaces”. Within the project, we will use density functional theory to study the impact of structural defects, such as dislocations, voids, etc., as well as the impact of chemical defects (i.e., contamination), on the electronic structure of molecule/metal interfaces. Such defects can be of high relevance, e.g., for organic electronics, where they potentially lead to the formation of “hot spots” that later lead to accelerated device degradation. A major challenge in the context of this project, however, is that the nature and the quantity of these defects is completely unknown. In order to elucidate these, we will develop a tailored first-principles structure search algorithm.

Oliver T. Hofmann was granted a three-year stand-alone project by the Austrian Science Fund FWF. Within the project, entitled “Interaction Strength Tuning at Inorganic/Organic Interfaces”, a post-doc and a PhD student will be employed to study charge transfer at interfaces between organic molecules and coinage metals semiconductors. Such interfaces are of high technological relevance for organic electronics as well as for catalysis. Interestingly, semiconductor and metal substrates seem to induce very different charge-ordering phenomena. Using doping to make semiconductors gradually “more metallic”, and alloying to make coinage metals “less metallic”, the transition between the differently ordered phases will be studied using various computational methods, including density functional theory and post Hartree-Fock methods.
Georg Urstöger has won a stipend from the Styrian Chamber of Commerce for master thesis that have a strong bond to industrial research. The granted thesis, "Proton Conductive Polymers deposited by Plasma Enhanced Chemical Vapor Deposition”, focuses on the production of proton conductive membranes to be used in the fuel cell industry. Proton conductive membranes are the heart of the fuel cell that allows the protons to permeate but block the electrons which are guided through an external circuit to generate electricity. The technique we use is plasma enhanced chemical vapor deposition (PECVD) which due to its nature has many advantages such as the tendency to produce crosslinked, stable polymers. The outcome of this thesis is to create a product that is feasible in cost but incorporates the good qualities of the currently best choices such as Nafion®.

Marie Curie Fellowship for Dr. Anna Maria Coclite >> more >>
Anna Maria Coclite was awarded a Marie Curie International Incoming Fellowship within the 7th European Community Framework Programme. The fellowship funds top-class researchers from non-European Countries to work on projects in Europe. The granted project, "Smart multi Stimuli-responsive Supports for controlled cell growth (Three S) " , aims to the development of a material that respond to several external stimuli such as humidity, light and temperature. Multi-stimuli responsive materials have not been widely investigated because they require fine control over the material composition and response. The material will be obtained by initiated Chemical Vapor Deposition (iCVD), a method, invented at MIT, that allows obtaining thin films with high versatility. The envisioned outcome will be that the water uptake of the material changes with the afore-mentioned stimuli, resulting in stiffness change.

Tuning the Threshold Voltage in Organic Thin-Film Transistors >> more >>
The insertion of a thin photoacid generator layer between the dielectric and the active layer in organic thin-film transistors (OTFTs) allows control of the threshold voltage through UV illumination by means of interfacial channel doping.

Chemisorbed conjugated molecules allows controlling interface electronic structure >> more >>
Charge-transfer monolayers hold a high potential for modifying carrier-injection properties of electrodes in organic electronics. A particular promising molecule in this context is HATCN. The electronic properties of HATCN on Au(111), however, display a very unexpected dependence on film thickness with a work-function increase setting in only for films thicker than 3 Angstrom. In a study joining groups from Berlin, Graz, Mainz, and Groningen, this peculiar behavior could be clarified by combining various experimental techniques with quantum-mechanical modeling. It was attributed to an unprecedented complete change in the film structure with layer thickness.
Circuits such as a seven stage ring oscillator and a four bit code generator were built using self-assembled monolayer field effect transistors (SAMFETs) grown on a polymer surface. This demonstrates the feasibility of using SAMFETs on flexible substrates.

Charge transport in self-assembled monolayer field-effect transistors >> more >>
The mobility of self-assembled monolayer field-effect transistors (SAMFETs) traditionally decreases dramatically with increasing channel length. Recently, however, SAMFETs using liquid-crystalline molecules have been shown to have bulk-like mobilities that are virtually independent of channel length. Here, we reconcile these scaling relations by showing that the mobility in liquid crystalline SAMFETs depends exponentially on the channel length only when the monolayer is incomplete. We explain this dependence both numerically and analytically, and show that charge transport is not affected by carrier injection, grain boundaries or conducting island size. At partial coverage, that is when the monolayer is incomplete, liquid-crystalline SAMFETs thus form a unique model system to study size-dependent conductance originating from charge percolation in two dimensions.
The ultimate miniaturization of electronics would be to use single molecules as electronic components. In a recent Nanoletters article, a team from M.I.T., Humbolt University, Montan University, Georgia Tech, and the TU Graz, explain why exchanging a single carbon atom with a nitrogen atom in certain molecules increases the electrical conductivity of the molecules by more than two orders of magnitude. The results provide clear guidelines for the rational design of single-molecule metals and highly doped single-molecule semiconducting devices. This is important for the development of bio-compatible interfaces between inorganic and organic matter. The image visualizes the transport channel in one of the studied molecules, a boron doped dithiol derivative of pyrene where the thiol groups are separated from the π-conjugated core by a methylene (i.e., -CH2-) spacer.

An aqueous dispersion of semiconducting polymer nanospheres was used to fabricate polymer light-emitting devices by inkjet printing in an easy-to-apply process with a minimum feature size of 20 μm. To form the devices, the electroluminescent material was printed on a nonemitting polystyrene matrix layer and embedded by thermal annealing. The process allows the printing of light-emitting thin-film devices without extensive optimization of film homogeneity and thickness of the active layer.Evelin Fisslthaler, Stefan Sax, Ullrich Scherf, Gernot Mauthner, Erik Moderegger, Katharina Landfester, and Emil J. W. List, Inkjet printed polymer light-emitting devices fabricated by thermal embedding of semiconducting polymer nanospheres in an inert matrix, Appl. Phys. Lett. 92, 183305 (2008)
An article on a new method for nanostructure formation from conjugated polymers appeared on the December 2008 inside cover of Soft Matter. An aqueous dispersion of semiconducting polymer nanospheres (SPNs) was deposited by inkjet printing onto a polymer surface patterned by soft embossing. By interaction between the spheres and the undulated surface a self assembly process is triggered, resulting in the formation of SPN nanostructures determined by the template. Both template layer and assembled SPNs can be incorporated into a device structure. We demonstrate a light emitting structure for use in polymer light emitting devices including analyses by atomic force microscopy and Kelvin probe force microscopy.

On July 16 2008, the institute made an excursion to the scientific instrument maker Anton Paar.
A research team from The Netherlands, Austria, Russia, and Germany announced a breakthrough in the development of organic electronic integrated circuits in the October 16, 2008 issue of the journal Nature. Self-Assembled Monolayer Field Effect Transistors (SAMFETs) were used to build circuits including a 15-bit code generator consisting of over 300 transistors. A critical layer of the SAMFETs consisted of a single molecular layer of quinquethiophene molecules which self-assembled into an ordered two-dimensional crystal. Although they are not as small or as fast as state-of-the-art silicon transistors, the self-assembly of molecules into useful devices is considered the ultimate technology for mass production and this is an important demonstration of how self-assembly can be used in the fabrication of a complex circuit. Organic transistors such as this are most useful in applications where transistors are distributed over a large area such as they are in a display.

A new diffusion mechanism observed in the growth of organic thin films >> more >>
In the July 3, 2008 issue of Science magazine, a team from the Montan University in Leoben and the TU Graz explained the growth of ordered thin films of parahexaphenyl. When molecules of parahexaphenyl are evaporated on clean a clean mica surface, the molecules form crystalline needles. Within the needles the molecules are ordered in straight rows with the molecules lying flat on the mica surface.
When the surface of the mica is bombarded with ions before the parahexaphenyl is deposited, the molecules stand up on the surface. Islands of the molecules have a stepped structure where the steps are one molecule high.
The form of the island is partially determined by the difficulty that the molecules have in diffusing over the edges of the steps. The energy barrier that the molecules must overcome to go over a step is known as the Ehrlich-Schwoebel barrier. Numerical simulations show that the molecules bend when they go over a step edge. The energy it takes to bend the molecules is an important contribution to the Ehrlich-Schwoebel barrier.

Surface plasmon coupled electroluminescent emission >> more >>
Surface plasmons are waves that appear at the surface of a metal. Light and electrons are coupled in these waves such that the light intensity and electron density go up and down together. Surface plasmon devices that process optical signals can be smaller than ordinary optical devices since the wavelength of the plasmons is shorter than the wavelength of light.
Inkjet-printed photodetectors operating at wavelengths up to 3 μm
were made using HgTe nanocrystals. Detectors operate in a spectral region of particular importance for biological applications, remote sensing and
night-vision imaging. A room temperature detectivity of D* = 3.2 × 1010 cm Hz1/2W–1 close to the important telecommunication wavelength region was observed.
