Abstract
A three-terminal quantum well device, which functions somewhat analogously to an MOS transistor. That is, the three terminals of the device can generally be considered as source, gate, and drain. An output contact is connected by tunneling to a number of parallel chains of quantum wells, each well being small enough that the energy levels in the well are quantized discretely. In each of these chains of wells, the second well is coupled to a common second conductor, and the first well is electronically coupled to a common first conductor.
