p-type semiconductor is obtained by doping  

A

germanium with arsenic

B

germanium with aluminium

C

germanium with antimony

D

germanium with phosphorus

Text Solution

Verified by Experts

The correct Answer is:
B
p - type semiconductor is obtained when silicon or germanium is doped with trivalent impurity like aluminium (Al), indium (In), boron (B) etc whereas n - type semiconductor is obtained when silicon or germanium is doped with pentavalent impurity like arsenic (As), antimony (Sb), phophorus (P) etc.
