  1. Let n electrons in a semiconductor. Under the electric field ‘E’ they are drifted with a drift vd. E Holes Electrons Drifting charge carrier in a semiconductor

  2. Then current density Where e is the charge of an electron. Then conductivity

  3. The drift velocity is also given by Where is the mobility of electrons. Substituting the above values,

  4. In case of semiconductor, the drift current density due to electrons is given by Then the total drift current density

  5. For an intrinsic semiconductor, n = p = ni, then
