The barrier potential of a p-n junction depends on:
(a) type of semiconductor material
(b) amount of doping
(c) temperature
Which one of the following is correct?
(a) type of semiconductor material
(b) amount of doping
(c) temperature
Which one of the following is correct?
A
(a) and (b) only
B
(b) only
C
(b) and (c) only
D
(a), (b) and (c)
Detailed Solution
The barrier potential depends on the semiconductor material (about 0.7 V for Si and 0.3 V for Ge), on the amount of doping and on temperature.
So all three factors (a), (b) and (c) matter.
So all three factors (a), (b) and (c) matter.
