Multiple layer quantum well FET with a side-gate
An exemplary FET includes a substrate and multiple vertically stacked layer groups with each layer group having a quantum well semiconductive layer and a nonconductive layer adjacent the first quantum well semiconductive layer. Conductive source and drain electrodes in conductive contact with the semiconductive layers. A 3-dimensional ridge of the stacked layer groups is defined between spaced apart first and second trenches which are between the source and drain electrodes. A continuous conductive side gate is disposed on the sides and top of the ridge for inducing a field into the semiconductive layers. A gate electrode is disposed in conductive contact with the conductive side gate.
