Definitions for "Field-effect transistor"
A transistor consisting of a source, a gate, and a drain. Current flow is controlled by the transverse electric field under the gate.
(sc) a transistor consisting of a source, gate and drain, whose action depends on the flow of majority carriers past the gate from the source to the drain. The flow is controlled by the transverse electric field under the gate.
A transistor whose control, or gate, signal creates an electro-magnetic field which turns the transistor ON or OFF.
