Question

Doping is necessary in order to enhance conduction ability of a semiconductor. Support this statement by giving suitable arguments?

Answer 1

Answer:

Because the band gap is so small for semiconductors, doping with small amounts of impurities can dramatically increase the conductivity of the material. Doping, therefore, allows scientists to exploit the properties of sets of elements referred to as “dopants” in order to modulate the conductivity of a semiconductor.
