Research focus areas and projects

Research focus and projects

The research work carried out by the Applied Semiconductor Physics working group is mainly organised in the form of externally funded projects. It is divided into the following areas:

 

Physics of Group III nitrides

    • Reduction of defect densities
    • Optimisation of the quantum yield of QW structures
    • Investigation of In incorporation in GaInN quantum films with high In content
    • Investigation of In incorporation in GaInN quantum films on non-polar surfaces
    • Development of efficient UV emitter structures

Material technology of Group III nitrides

    • Microscopic causes of radiative recombination in nitrides
    • Non-radiative recombination processes and defects in nitrides
    • Mechanisms of optical amplification in nitrides
    • Spontaneous and piezoelectric polarisation fields
    • Surfaces and adsorbates in III-nitrides
    • Green laser diodes
    • Green light-emitting diodes
    • UV light-emitting diodes

Self-organised quantum dots

    • Optical properties of InP/GaInP quantum dots
    • Red-emitting quantum dot lasers
