My research activities can be divided into different but related topics

  • Time resolved Photoluminescence Spectroscopy
  • Recombination Processes in Wide Bandgap Semiconductors
  • Material Development of Wide Bandgap Semiconductors towards Device Applications  
  • Device Critical Defects and Material Properties of Widebandgap Semiconductors

My initial research was about time resolved photoluminescence studies of different semiconductor materials. This includes studies of recombination processs and recombinations related to different defects in the material.

From characterisation of carrier lifetimes in SiC, which is an important material property of power devices, the research has broadend to a general research of defects and material properties important for semiconductor device applications. Today this includes mainly SiC for power applications and Nitrides for opto- and high frequency- applications.

Together with the optical spectroscopy of semiconductor material, I am also involved in structural and electrical characterisation to understand critical and limiting defects. I am also involved in material growth and material development, with a focus on issues critical for different device applications. 

See further under Research, in the left meny, which includes recent Research Highlights, Research Laboratories, and Tutorial, which are basic explenations about characterisations techniques and motivation for the research.:
