An n-type and p-type silicon can be obtained by doping pure silicon with.

Options

A. arsenic and phosphorous respectively
B. indium and aluminium respectively
C. phosphorus and indium respectively
D. aluminium and boron respectively

Answer

C

Explanation

To form an n-type semiconductor doping is done by using a pentavalent impurity, like phosphorous and to form a p-type semiconductor doping is done by using a trivalent impurity like indium.
