Light and Electricity from Novel Semiconductors (LENS) / The Semiconductor Physics Group
The overall vision is “application-motivated basic research” where we address rather fundamental materials science and physics issues but in most cases with a clear vision for long-term applications relevant to enabling technologies for renewable energy. On a more detailed level, a central ingredient is to cover the whole ‘value-chain’ from materials synthesis to realization and evaluation of test (device) structures.

LENS comprises currently about 18 externally funded projects and key areas are:
- Wide bandgap semiconductors and transparent conductive oxides (especially, ZnO, SiC and Indium-Tin-Oxides) (specific headlines are “synthesis”, “doping”, “defects”, “gate dielectrics”, “radiation detectors”, “devices for solid state lightening”, “photovoltaics and new generation solar cells”, and “photo-electrical-conversion”)
- Semiconductor nanoscience/technology (“ embedded nanocrystals”, “porous Si”, “thermoelectric materials”, and “ion-beam nanostructuring”)
- High and medium purity Si (“solar cells”, “radiation detectors”, ”shallow junctions”, “point defects and diffusion”)
- (N)MEMS and MOEMS (Nano/Micro-Electrical-Mechanical-Systems including tuneable optical filters, actuators, and pressure sensors for medical applications).
LENS has a high international visibility, as manifested by invited talks at leading international conferences, invited review articles, research awards, and numerous international collaborators and projects. LENS also plays a central role in the Norwegian Centre for Environmental Energy Research on Solar Cell Technology, awarded by the Norwegian Research Council and involving four research partners and nine industrial partners.
Scientifically, LENS has an annual output of ~20 journal papers and ~10 conference papers, ~4 PhD candidates, ~4 MSc candidates, ~2 patent applications and declarations of inventions.
