Question

In a semiconductor, current conduction is due to_________.

Answer 1

Semiconductors:-

1. It is actually a device which is having a conductivity between conductors which are generally metals and non-conductors such ac ceramic.
2. Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon .

Holes and Electrons in Semiconductors:-

1. Holes and electrons are the charge carriers that allow the flow of current in semiconductors.
2. Holes are the positively charged electric charge carrier.
3. Electrons are negatively charged particles.
4. In a semiconductor, current conduction is because of both holes and electrons.
5. In the P-type region, holes are the majority carriers and electrons are the minority carriers.
6. In the N-type region, electrons are the majority carriers and holes are the minority carriers.

Therefore, In a semiconductor, current conduction is due to:- both holes and electrons.
