Metal-Oxide-Semiconductor Field-Effect Transistor

Introduction
The metal-oxide-semiconductor field-effect transistor or MOSFET is by far the most common field-effect transistor in both digital and analog circuits.
The MOSFET is composed of a channel of n-type or p-type semiconductor material, and is accordingly called an nMOSFET or a pMOSFET.
Usually the semiconductor of choice is silicon, but some chip manufacturers have begun to use a mixture of silicon and germanium (SiGe) in MOSFET channels. Unfortunately, many semiconductors with better electrical properties than silicon, such as gallium arsenide, do not form good gate oxides and thus are not suitable for MOSFETs.
