Question:

The barrier potential of a p-n junction depends on which of the following?

Options:

Material of the semiconductor

amount of doping

temperature

all the above

Correct Answer:

all the above

Explanation:

Different types of semiconductor have different barrier potential. (Eg : GaAs and Si)
Amount doping affects the no. of majority carriers hence the barrier height.
Temperature increases the thermally generated carriers.
