Question

$Si$ becomes a $p-$ type semiconductor when doped with group $13$ element $(Al,Ga)$.

• A. True
• B. False

Answer 1

The correct option is A True

p -type semiconductor: The semiconductor whose increased in conductivity is a result of electron-hole is called a p -type semiconductor. When a crystal of group 14 elements such as Si or Ge is doped with a group 13 element such as B, Al, or Ga (which contains only three valence electrons), a p - type of semiconductor is generated.
