Question

The conduction band edge in the p material is not at the same level to that of conduction band edge in the n material. Is it true or false?

(a) True

(b) False

This question was posed to me by my college director while I was bunking the class.

I would like to ask this question from Band Structure of an Open-Circuited p-n junction in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

The correct option is (a) True

Explanation: In a p-n junction diode, the energy levels of the p material and n material will not be at same level. They will be different. So, the conduction band edge as well as the valence band edge of the p material will not be same to that of the n material.
