  • Transferred electron effect device
    Patent number: 5258624
    Abstract: A transferred electron effect device has a semiconductor body with an active region (2) of n conductivity type formed of a semiconductor material having a relatively low mass, high mobility conduction band main minimum and at least one relatively high mass, low mobility conduction band satellite minimum, and an injection zone (3) adjoining the active region (2) for causing electrons to be emitted, under the influence of an applied electric field, from the injection zone (3) into the active region (2) with an energy comparable to that of the relatively high mass, low mobility, conduction band satellite minima of the active region.
