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 ...

By contrast, conductors have a band gap that is narrow to nonexistent. Semiconductors are sometimes considered to be insulators with narrow band gaps. For a visual explanation of N-type versus P ...

Semiconductor Physics and Flat Band Potential Semiconductors are materials with electrical properties that lie between those of conductors and insulators ... separated by an energy gap. Electrons in ...
