The barrier potential of a p-n junction depends on : (i) type of semiconductor material (ii) amount of doping (iii) temperature.
Which is one of the following is correct?

Options

A. (1) and (2) only
B. (2) only
C. (2) and (3) only
D. (1), (2) and (3)

Answer

D

Explanation

The barrier potential depends on type of semicondutor (For `Si, V_(b)=0.7V` and for Ge, `V_(b)=0.3V`), amount of doppping and also on the temperature.
