 # In a semiconductor, current conduction is due_________

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

## Semiconductors

Semiconductors are the materials which have a conductivity between conductors which are generally metals and non-conductors or insulators such as ceramics. Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon. Physics explains the theories, properties and mathematical approach governing semiconductors.

### Holes and Electrons in Semiconductors

Holes and electrons are the types of charge carriers accountable for the flow of current in semiconductors. Holes are the positively charged electric charge carrier whereas electrons are the negatively charged particles. Both electrons and holes are equal in magnitude but opposite in polarity.

• In a semiconductor current conduction is due to both holes and electrons.
• In p-type materials holes are in larger number compare to free electrons, and they are the majority carriers.
• In N-type, free electrons are the majority carriers. (1) (0)
