Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...

Research team led by Dr. Seo at KERI develops radiation resistance evaluation technology for SiC power semiconductors.

However, this would only be possible by using wide-band-gap semiconductors, which have not been considered for solar cells used for land-based applications because their band gaps are too large.
