Normally, semiconductors don't have many free electrons. Since electric current relies on those free electrons, the amount of current that can travel through an isolated semiconductor is negligible.
This course presents in-depth discussion and analysis of metal-oxide-semiconductor field-effect transistors (MOSFETs) and bipolar junction transistors (BJTs) including the equilibrium characteristics, ...
Two distinct structures have been developed for the enhancement mode of GaN-based high-electron–mobility transistors (HEMTs). These two modes are the metal-insulator–semiconductor (MIS) structure, 2 ...
