metal-semiconductor field-effect transistor (MESFET)

A field-effect transistor in which a metal-semiconductor rectifying contact is used for the gate electrode.

NOTE 1 Typically the structure is fabricated in gallium arsenide and the term GaAs MESFET may be used.

NOTE 2 Both depletion-type and enhancement-type devices have been manufactured. The acronyms are D-MESFET and E-MESFET, respectively.
