In which of the following statements, the obtained impure semiconductor is of 
-type?
Text Solution
Verified by ExpertsThe correct answer is:
C
p-type semiconductor is obtained when silicon (Si) or germanium (Ge) is doped with trivalent impurity like, boron(B), aluminum (Al), gallium (Ga) etc. 
-type semiconductor is obtained when silicon (Si) or germanium 
is doped with pentavalent impurity like arsenic (As), antimony(Sb), bismuth(Bi) etc.
