Dear student,
◆ Answer -
(II) Holes are the majority carriers and trivalent atoms are the dopants.
● P-type semiconductor -
- Typical trivalent (column III) impurity is added to silicon/germanium.
- Usually Boron/Aluminium is used as doping material.
- Holes are the majority carriers in p-type semiconductors.
Hope this is helpful to you. Thanks dear for asking.
