Resistances and their Measurements,rriers of electricity are negatively charged free electrons. In semiconductors such as silicon there are two types of carriers, namely free electrons and positive holes. If silicon, a group IV element, is doped with elements of the fifth group, such as arsenic or phosphorus, the concentration of fre

Insulated-Gate-Field-Effect-Transistor (IGFET),e physics needed to describe the fundamentals of the insulated gate field effect transistor (IGFET).. If the appropriate voltage is applied to the gate of an MIS structure, an inversion layer can be formed on the surface of the semiconductor composed of carriers which are, by definition, of the oppo
