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.
