Abstract
The present invention provides a single-electron transistor device. The device comprises a sourceand drainlocated over a substrateand a quantum islandsituated between the source and drain, to form tunnel junctionsbetween the source and drain. The device further includes a fixed-gate electrodelocated adjacent the quantum island. The fixed-gate electrode has a capacitance associated therewith that varies as a function of an applied voltage to the fixed-gate electrode. The present invention also includes a method of fabricating a single-electron device, and a transistor circuitthat include a single-electron device
