Question

Draw the energy band diagram when intrinsic semiconductor (Ge) is doped with impurity atoms of Antimony (Sb). Name the extrinsic semiconductor so obtained and majority charge carriers in it.

Answer 1

This is an n-type extrinsic semiconductor. Majority charge carriers are electrons.

Answer 2

Well labelled energy band diagram of n-type semiconductor 

n-type semiconductor 

electrons-majority charge carriers

Answer 3

An extrinsic semiconductor which has been doped with e^- donor atom is called a n-type semiconductor due to the majority of charge.

Answer 4

Semiconductor: n-type

Majority change carriers: electrons
