Abstract:

An apparatus includes a field-effect transistor (FET). The FET includes a region of first semiconductor and a layer of second semiconductor that is located on the region of the first semiconductor. The layer and region form a semiconductor heterostructure. The FET also includes source and drain electrodes that are located on one of the region and the layer and a gate electrode located to control a conductivity of a channel portion of the semiconductor heterostructure. The channel portion is located between the source and drain electrodes. The gate electrode is located vertically over the channel portion and portions of the source and drain electrodes.

US Classification:

257 14, 257E43003, 257E43007

Abstract:

An apparatus includes a substrate with a planar surface, a multilayer of semiconductor layers located on the planar surface, a plurality of electrodes located over the multilayer, and a dielectric layer located between the electrodes and the multilayer. The multilayer includes a 2D quantum well. A first set of the electrodes is located to substantially surround a lateral area of the 2D quantum well. A second set of the electrodes is controllable to vary a lateral width of a non-depleted channel between the substantially surrounded lateral area of the 2D quantum well and another area of the 2D quantum well. A third set of the electrodes is controllable to vary an area of a non-depleted portion of the lateral area.
