Energy level alignment at organic/metal interfaces: The role of dielectric layers
Michael Hollerer, Institute of physics, University of Graz

While organic electronics are on the verge of becoming a major industry the underlying principles on a molecular level are still under debate. Within our work we aim to gain a better insight into the alignment of the electronic levels of organic molecules on metal and dielectric/ ... more

Light Confinement in Corrugated Organic Solar Cells
Florian Kolb, JOANNEUM RESEARCH MATERIALS – Institute for Surface Technologies and Photonics

Organic solar cells are concerning their production costs, scalability to industrial fabrication and their versatility in terms of application advantageous when compared to their inorganic counterparts. On the other hand, they still suffer in terms of a significantly lowered perf ... more

Indirect Measurement of the Self-Modulation Instability of a Long Proton Bunch in Plasma
Marlene Turner , CERN / TU Graz
https://docs.google.com/presentation/d/1IFFqyBfUVKeZfeAfqkiW_sn3A12JtLcOb2uNZ90R_as/edit?usp=sharing

The AWAKE experiment at CERN aims to create GV/m plasma wakefields over a length of 10 m by using a self-modulated 400 GeV/c proton drive beam from the CERN Super Proton Synchrotron (SPS). The first AWAKE run taking place in 2016 and 2017 is dedicated to study the physics and de ... more

Improving the Applicability of Density Functional Theory Simulations for the Description of Metal-Organic Interfaces
Elisabeth Wruß, Institute of Solid State Physics, Graz University of Technology

Density functional theory (DFT) is one of the most widely used methods in computational material research, as it provides a good compromise between computational expenses and accuracy. Using standard semi-local DFT, comparably large systems containing several hundred or even thou ... more

Controlling the out-coupling behavior of organic light emitting diodes by smartly designed aluminum plasmonics
Manuel Auer-Berger, JOANNEUM RESEARCH MATERIALS – Institute for Surface Technologies and Photonics

The generation of artificial light has occupied generations of scientists throughout the history of mankind and only recently culminated in the development of light emitting diodes, a high efficiency technology which is based on the radiative recombination of injected electron-ho ... more

Adsorption and Decomposition of Methanol on mixed CuO-CuWO4 oxide surfaces
Matthias Blatnik, University of Graz

The catalytic properties of methanol (CH3OH) adsorbed on clean and oxygen covered Cu(110) have been intensively investigated over the last thirty years. Besides of being generally important for the chemical industry (e.g.[1, 2]), methanol is of great interest as a “smart” pro ... more

Suppressing Short-Channel Effects by Schottky barrier manipulation
Antón Fernández, Institut of Solid State Physics

High switching speeds constitute one of the optimization targets for organic thin film transistors (OTFT). Reducing the OTFTs channel length is a major handle to boost the switching speed. However, upon reducing the channel length one has to cope with undesired short-channel effe ... more

Reliability aspects of chip to chip interconnections
Christian Hartler, ams AG

3D interconnection technologies significantly improve the versatility of integrated circuits since different functions can fit in smaller space by chip stacking. This allows further implementation of integrated chips in daily objects. Key end user applications are Internet of Thi ... more

CMOS integrable metal oxide gas sensors
Robert Wimmer-Teubenbacher, Materials Center Leoben

In recent years the demand for cheap, easy to manufacture and low power consuming gas sensors has grown. Gas sensors are employed in indoor and outdoor air quality monitoring [1], smoke gas detection (e.g. fire, heating) [2], automobile industry (e.g. cabin, exhaust) [3], and man ... more

Direct-Write Fabrication of Electric and Thermal High-Resolution Nanoprobes on Self-Sensing AFM Cantilever
Jürgen Sattelkow, PhD. Student at FELMI

Atomic Force Microscopy (AFM) has evolved into an essential part in research and development due to its quantitative 3D surface characterization capability and additional AFM modes, which provide laterally resolved electric, magnetic, chemical, mechanical, optical, or thermal pro ... more
