Abstract:
1. A nonvolatile memory device, comprising: a modulation doped field-effect transistor (MODFET) structure having a source, a drain, a gate region and a semiconductor substrate in which a transport channel is formed between the source and the drain, wherein the transport channel is controlled by a voltage applied to the gate region, wherein the gate region includes a multilayer structure having: a first layer located proximate to the transport channel, wherein the transport channel is constructed from at least one material selected from the group consisting of an insulator and a wide energy gap lattice matched semiconductor and a pseudomorphic semiconductor layer, wherein the first layer serves as a spacer layer, a second layer located proximate to the first layer, wherein the second layer is constructed from a doped semiconductor material having donor impurities that provide electrons as a supply layer to the transport channel, a third layer located proximate to the second layer wherein the third layer includes a semiconductor layer having acceptor type impurities, and a first set of cladded quantum dots assembled on the third layer, wherein the first set of cladded quantum dots is selected from a group consisting of SiO
