ABSTRACT
A semiconductor is a material that has electrical conductivity to a degree between that of a metal (such as copper) and an insulator (such as glass). Semiconductors can be divided

into two major types: intrinsic and extrinsic semiconductors. The former is diamond cubic and the latter is zinc blend. The electric conductivity of intrinsic semiconductors can be enhanced by doping metallic oxides, transition metal oxides, or nonmetallic oxides. These methods result in the formation of extra electrons or holes, which can be assigned as N-type or P-type semiconductors.5
