" If "n_(e)" and "v_(d)" be the number of electrons and drift velocity in a semiconductor.When the temperature is increased "

If n_(e) and n_(h) be the number of electrons and drift velocity in a semiconductor. When the temperature is increased

If N_(P) and N_(e) be the numbers of holes and conduction electrons in an extrinsic semiconductor, then

The relation between number of free electrons (n) in a semiconductor and temperature (T) is given by

Under an extemal electric field electrons drift slowly inside the conductor. When temperature increases what happens to drift velocity?

What is drift velocity (v_(d)) ?
