In case of intrinsic semiconductor
WebAn intrinsic type of semiconductor material is made to be very pure chemically. It is made up of only a single type of element. Conduction Mechanism in Case of Intrinsic … An intrinsic (pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic … See more In an intrinsic semiconductor such as silicon at temperatures above absolute zero, there will be some electrons which are excited across the band gap into the conduction band and which can support charge flowing. … See more The current which will flow in an intrinsic semiconductor consists of both electron and hole current. That is, the electrons which have been freed from their lattice positions into the … See more • Extrinsic semiconductor See more
