3C SiC: Synthesis, Surface Properties and Application in Hybrid Solar Cells
Olivia Kettner, Institute of Solid State Physics

Silicon carbide (SiC) is an attractive material for applications in different fields spanning from high power electronics to material engineering, due to its versatile properties as high-temperature stable wide-band gap semiconductor, enormous chemical stability and high hardness ... more

Understanding surface enhanced Raman spectroscopy using accurate nearfield-simulations of real substrates
Harald Fitzek, Institute for Electron Microscopy and Nanoanalysis (FELMI), Graz University of Technology (TU Graz), NAWI Graz, Steyrergasse 17, 8010 Graz, Austria

Surface enhanced Raman spectroscopy (SERS) is a powerful technique that uses metal nanostructures to enable the analysis of monolayers and even single molecules adsorbed on the metal surface. This is possible because of the strong enhancement of the electric nearfield close to su ... more

How Sample Holder Geometries Influence the Quantification of X-ray Spectra
Judith Lammer

Energy-dispersive X-ray spectrometry (EDXS) is a widely used method for the analysis of samples and their quantification in transmission electron microscopy. Although it is a fast and efficient way to do elemental analysis, it gets tricky, when it comes to measuring light element ... more

Understanding the adsorption of non-planar Subphthalocyanine molecule on the Cu(111) surface
Shashank S. Harivyasi, Institute of Solid State Physics, NAWI Graz, Graz University of Technology

We know that the structure of an organic molecule plays a determining role in its adsorption on metal surface and on the subsequent interaction between them. However, the case can be quite complex for non-planar molecules which show a varying tendency in planarization upon adsorp ... more

Ab-initio simulation of strongly correlated materials with large spin-orbit coupling
Gernot Kraberger

In materials containing heavy transition metal atoms with open d-shells, electronic correlations and spin-orbit coupling (SOC) play an important role. The interplay of these two ingredients can drastically alter the physics and give rise to interesting phenomena. It is therefor ... more

Polymers by initiated Chemical Vapor Deposition - From Drug Coatings to Polymer Electrolyte Membranes
Paul Christian

From abundant biopolymers like cellulose to synthetic anti-adhesive coatings of polytetrafluoroethylene (PTFE), a tremendous variety of chemistries and a wide range of properties are accessible with polymeric materials, making them ubiquitous in everyday life. Synthetic polymers ... more

Fork Tensor Product States - Multi-orbital Dynamical Mean Field Theory on the real frequency axis
Daniel Bauernfeind, Institute for Computational Physics

Dynamical Mean Field Theory (DMFT) is a powerful method for ab initio description of strongly correlated materials. In such materials the electron-electron interactions cannot be neglected, giving rise to interesting phenomena such as Mott-insulators or Kondo physics. State of th ... more

Bismuthates under high pressure. Ab-initio study
Andriy Smolyanyuk

At ambient pressure ABiO$_3$ (A=Ba,Sr,Ca) bismuthates are 3D charge density wave (CDW) insulators, exhibiting insulator to metal transition upon hole doping and supeconductivity with T$_c$'s up to 34$~$K can occur in the metallic phase. However, little is known about their high-p ... more

Spin-orbit coupling and correlations in a 3-band model system
Robert Triebl

In materials with sizable electron-electron correlation, such as perovskites with open d-shells, for example, the effective mass of the quasiparticles is enhanced. At some critical interaction strength, a metal insulator transition (Mott transition) takes place as the effective m ... more

Surface induced phases: origin and stability on the example of pentacene
Stefan Pachmajer

The presence of a surface during the crystallisation of molecular materials can induce previously unknown types of polymorphic crystal structures, known as surface induced phases (SIPs) or surface mediated polymorphs. These types of crystal structures are only stable for a limit ... more
