In semiconductors, electrons and holes are charge carriers that facilitate electrical conductivity; electrons are negatively charged particles, while holes are the absence of an electron in a lattice, acting as positively charged particles. The movement of electrons and holes in response to electric fields underpins the operation of electronic devices such as diodes and transistors.

Electrons And Holes

Semiconductors are materials with electrical conductivity between that of a conductor and an insulator, crucial for modern electronics. They are the foundation of integrated circuits and devices like transistors, enabling the miniaturization and performance enhancement of electronic technologies.

Charge carriers are particles or quasiparticles that carry electric charge, essential for the conduction of electricity in materials. In conductors, charge carriers are typically electrons, while in semiconductors, they can be electrons or holes, and in electrolytes, they are ions.

charge carriers

Electrical conductivity is a measure of a material's ability to allow the flow of an electric current, which is determined by the availability and mobility of charge carriers such as electrons or ions. It is a critical property in determining the suitability of materials for applications in electronics, energy transmission, and electrochemical processes.
