Question

Give difference between ntype and ptype semiconductor

Answer 1

n type semiconductor

* The electrons density (ne) is much greater than the hole density (nh) i.e.>> nh.

* The donor energy level is close to the conduction band and for away from the valence band.

* The Fermi-energy level lies in between the donor energy level and conduction band.

p type semiconductor

*The holes density (nh) is much greater than the electrons density (ne) i.e.>> ne.
*The acceptor energy level is close to the Valence band and for away from the Conduction band.

* The Fermi-energy level lies in between the acceptor energy level and valence band.
