Question

If in a n-type semiconductor when all donor states are filled, then the net charge density in the donor states becomes
(a) 1
(b) > 1
(c) < 1, but not zero
(d) zero

Answer 1

Answer:

(b)

Explanation:

When all donor states in n-type semiconductor are filled, the number of electrons in donor states will increase. Due to it, the charge density in donor states will become more than one.
