Semiconductor Principles - Technical MCQs

Q1:

The natural elements carbon, germanium, and silicon are semiconductors.

A True

B False

ANS:A - True

1. Carbon is not a semiconductor, because according to the band theory a semiconductor have not band gap more than 1.1 ev.

2. Carbon have energy gap around 1.5 ev.

3. 6 ev band gap for diamond which is a well known allotrope of carbon.
