Warum und woran ich forsche
My research is dedicated to following projects:
- Characterization of novel (ternary) nitride semiconductors by scanning tunneling microscopy (STM) and spectroscopy (STS), e.g. GaN, InN, AlInN, AlGaN, etc.
- Defects in (light-excited) semiconductors and their influence on the electric properties
- Investigation of device structures like LEDs by STM
III-V compound semiconductor nanowires for future lighting applications or energy harvesting
Electrostatic potential of the STM tip located near the surface of a semiconductor. The potential is not completely screened at the semiconductor's surface and thus leads to the so-called tip-induced band bending. The image is based on a simulation performed in our STM group.
