Research overview

Driven by the need to reduce CO2 emission into our atmosphere, maximizing the energy efficiency, minimizing the use of hazardous materials, and promoting the harvest of renewable energy have come into focus of current research initiatives. There are several approaches, which tackle the problem from different angles (to name a few): Development of "better" materials, usage of less material, i.e. making devices smaller, accessing new functionalities/physical properties such as in phase change memories or spintronic devices, or changing complete architectures to enable efficient computing, for instance in quantum computing. In our group we investigate structural, electronic and bonding properties of nanomaterials and thin films by means of analytical (scanning) transmission electron microscopy ((S)TEM), energy dispersive x-ray spectroscopy (EDX) and electron energy loss spectroscopy (EELS), as well as by high resolution (S)TEM imaging techniques.

  • Making devices smaller: epitaxial high-k dielectrics grown on semiconductors such as GdScO3/GaN
  • Ferroelectric devices: doped HfLuO3
  • Towards Q-Bits: Nb layers grown on topological insulators such as Sb2Te3
  • Phase-change materials: Ge-Sb-Te alloys
  • Harvesting renewable energy: CIGS solar cells
