Question

Q82. Doping of germanium with arsenic leads to
(A) Conductor
(B) Insulator
(C) P-type semiconductor
(9) N-type semiconductor​

Answer 1

Answer:

If germanium doped with arsenic (five valence electrons), four are used in bonding and one electron will be left for conduction. This produces an n-type material. ... If germanium is doped with gallium (three valence electrons), all three electrons are used in bonding, leaving one hole for conduction.

hope this helps you ☺️

Answer 2

Answer:

N - type semiconductor
