Meaning
Charge carriers are charged particles that move through a substance when a potential difference]] (pd) is applied across it.
About Charge Carriers
- In metals, the charge carriers are electrons.
- In electrolytes, the charge carriers are ions.
- The movement of charge carriers constitutes an electric current.
- In semiconductors, charge carriers include both electrons and holes.
- The concentration and mobility of charge carriers affect the electrical conductivity of a material.
Charge carriers are fundamental in the operation of electronic devices such as transistors and diodes.
- Understanding charge carrier dynamics is crucial for designing and optimizing electrical and electronic systems.
