About myself
I am working on theoretical condensed matter physics focusing on spin quantum transport in semiconductors and carbon hetero- and nanostructures. I am mainly interested in their dynamic properties and to find schemes for possible spintronic applications.
During my PhD at the Technical University Graz (Austria) in the group of Prof. Ferdinand Schürrer I investigated charge transport within the semiclassical Boltzmann equation approach examining hot phonon effects in semiconductor heterostructures and carbon nanotubes.
In 2006 I joined the spintronic research group of Prof. Jaroslav Fabian at the University Regensburg (Germany) investigating coherent spin transport in magnetic semiconductor heterostructures as possible spintronic devices. As a second research line I studied the role of spin-orbit coupling on the band structure of graphene. We investigated possible mechanism which could explain the unexpected short spin relaxation time measured therein.
In 2010 I joined the solid-state group of Prof. Walter Pötz at the Karl-Franzens University Graz (Austria) working on spin transport in resonant tunneling structures comprising Ga(Mn)As quantum wells including disorder effects and investigating spin-selective transport in ferromagnetic half-metal/semiconductor (CrAs/AlAs) heterointerfaces employing the non-equilibrium Green's function approach.
Recently, I started to study the dynamic spin transport properties of topological insulator/ferromagnet heterostructures.
