Intrinsic Semiconductor

Intrinsic Semiconductor

Intrinsic Semiconductor A natural semiconductor is an undoped semiconductor. This implies holes in the valence band are vacancies made by electrons that have been thermally excited to the conduction band, rather than doped semiconductors where gaps(holes) or electrons are provided by an “outside” or (foreign) particle/atom going about as an impurity. They are so called (semiconductor) ... »

Semiconductors Theory

Semiconductors  Theory Semiconductors are usually classified by the energy gap between their valence band and the conduction band. The valence band is the band consisting of the valence electron, and the conduction band remains empty. Electrical Conduction takes place when an electron jumps from valence band to conduction band and the gap between these two bands is forbidden energy gap. Wider... »
