Schottky Barrier Gate Field Effect Transistor

Abstract

An obvious addition to the ever-growing family of field-effect devices is a field-effect transistor with a Schottky barrier gate. It is the purpose of this correspondence 1) to demonstrate that indeed such a device does function as expected and 2) to point out several advantages of such a structure under certain circumstances. A schematic cross section of the device is shown in Fig. 1. The gate consists of a metal in intimate contact with the clean semiconductor surface. Clearly the ohmic contacts can be placed either on top of or under the semiconductor layer.
