Abstract:
1. A three-terminal semiconductor transistor device, comprising: a) a base region formed by a semiconductor material of a first conductivity type at a first concentration, the base region being in contact with a first electrical terminal via a semiconductor material of the second conductivity type at a second concentration that is lower than the first concentration; b) a conductive emitter region in contact with the semiconductor base region, forming a first Schottky barrier junction at the interface of the conductive emitter region and the semiconductor base region, the conductive emitter region being in contact with a second electrical terminal; and c) a conductive collector region in contact with the semiconductor base region, forming a second Schottky barrier junction at the interface of the conductive collector region and the semiconductor base region, the conductive collector region being in contact with a third electrical terminal, wherein the tunneling current through the first Schottky barrier junction or the second Schottky barrier junction is substantially controlled by the voltage of the semiconductor base region.
