Pune silicon doped with phosphorus is

Question

Pune silicon doped with phosphorus is (A) amorphous (B)  p -type semiconductor (C)  n -type semiconductor (D) insulator

Tardigrade Admin · Accepted Answer

Doping means incorporating small amount of foreign impurity. Doping of group 14 elements such as silicon with group 15 elements such as phosphorus give rise to excess electrons are called n -type semiconductor (as negative charge flows).
