in p - type semiconductor ,holes are the majority carrier and electrons are the minority carriers . P -types semiconductor are created by doping an intrinsic semiconductor with acceptor impurities ( or doping an n -type semiconductor). A common p -type dopant for silicon in boron

Hey !!
P - TYPE SEMICONDUCTOR ==> When silicon or germanium is doped with a group 13 element like B or Al, the dopant atom forms 3 covalent bonds , but at the place of fourth electron a hole is created. This hole moves through the crystal like a positive charge giving rise to electrical conductivity. Thus , Si or Ge doped with B or Al is called p-type semiconductor ( P stands for +ve hole ), since it is the +ve hole that is responsible for conduction.
Example :- Boron , Gallium etc.
Hope it helps you !!
