NMOS transistorNegative-channel metal-oxide semiconductors (NMOS) employ a positive secondary voltage to switch a shallow layer of p-type semiconductor material below the gate into n-type. For positive-channel metal-oxide semiconductors (PMOS), all these polarities are reversed. NMOS transistors are more expensive, but faster, than PMOS transistors. — transistor NMOS transistor

The term transistor was coined in May 1948 by John Robinson Pierce, an electrical engineer at Bell Labs who was also a science-fiction author. The name is a portmanteau—a linguistic blend—derived from the words transfer and resistor.1

This name reflects the device's function as a solid-state component that transfers an input signal across a material with varying resistance to control or amplify electrical current.21
