Main Charge Carriers in Semiconductors

In semiconductors, the main carriers of charge are electrons and holes.

Semiconductors are materials with electrical conductivity between that of a conductor and an insulator. The behavior of charge carriers in semiconductors is crucial for understanding their electrical properties.

In semiconductors, electrons are the primary negative charge carriers, while holes are the primary positive charge carriers. When an electron moves from its position, it leaves behind a hole, which can be thought of as a positive charge carrier.

These charge carriers play a fundamental role in the operation of semiconductor devices such as diodes, transistors, and integrated circuits.
