Abstract

This invention describes a field-effect transistor in which the channel is formed in an array of quantum dots. In one embodiment the quantum dots are cladded with a thin layer serving as an energy barrier. The quantum dot channel (QDC) may consist of one or more layers of cladded dots. These dots are realized on a single or polycrystalline substrate. When QDC FETs are realized on polycrystalline or nanocrystalline thin films they may yield higher mobility than in conventional nano- or microcrystalline thin films. These FETs can be used as thin film transistors (TFTs) in a variety of applications. In another embodiment QDC-FETs are combined with: (a) coupled quantum well SWS channels, (b) quantum dot gate 3-state like FETs, and (c) quantum dot gate nonvolatile memories.
