A Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is a type of transistor used for amplifying or switching electronic signals, integral to modern electronic devices. Its operation is based on the control of the electrical conductivity of a channel in a semiconductor material through an electric field applied via a metal gate isolated by an oxide layer.

Metal-Oxide-Semiconductor Field-Effect Transistor

A MOSFET, or Metal-Oxide-Semiconductor Field-Effect Transistor, is a type of transistor used for amplifying or switching electronic signals in a wide range of devices. It operates by varying the width of a channel along which charge carriers, such as electrons, flow, making it a fundamental building block in modern electronic devices and integrated circuits.

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.

electrical conductivity

Semiconductor materials are essential for modern electronics, possessing electrical conductivity between that of a conductor and an insulator, which can be altered by the introduction of impurities. They are the foundation of devices like transistors, diodes, and solar cells, enabling the functionality of computers, smartphones, and other electronic systems.

semiconductor material

An electric field is a vector field around a charged particle that represents the force exerted on other charges placed within the field. The strength and direction of the electric field are determined by the magnitude and sign of the charge, as well as the distance from the charge.
