Increasing The Electrical Conductivity of the semiconductor by Doping and Heating

Abstract

In this research was done discussion of the semiconductor by details whence structure, refinement, types and conductivity. And charge carrier properties whence density, effective mass, and concentration in intrinsic and extrinsic semiconductor .Also found there’s proportioning between the carrier density and electrical conductivity, then increasing the density of this carrier increases the electrical conductivity of the semiconductor. Position of Fermi level in this research was determined. The heating and doping are increase the electrical conductivity of the semiconductor. The research was taken up germanium element the intrinsic semiconductor and subjugated to theoretical and practicalstudy
