Q1:

Which impurity atom will give p type semiconductor when added to intrinsic semiconductor?

A Phosphorus

B Boron

C Arsenic

D Antimony

ANS:B - Boron

@All.

Just remember BIG ( Boron, Indium, Gallium) for Trivalent that will give p-type semiconductor when added to pure semiconductor and PAA. (Phosphorus, Arsenic, Antimony) for Pentavalent that will give n-type semiconductor when added to pure semiconductor/ Intrinsic.
