Abstract:
A dual gate oxide channel field effect transistor assembly comprising:a crystal oxide substrate; a first layer comprising a conductive oxide which in said assembly forms a first gate electrode in continuous contact with said substrate; a second layer comprising a gate insulator formed from an oxide which in said assembly forms a first gate oxide, said second layer being aligned in continuous contact with said first layer; source and drain electrodes situated in contact with said second layer; said source and drain electrodes each having an upper surface and side areas which are in contact with a third layer comprising a Mott-material oxide layer which in said assembly forms a channel; the exposed surfaces of said Mott-material layer and the remaining non-contacted sides of said source and drain electrodes being enveloped by a fourth layer comprising a second gate insulator material; a second gate electrode in contact with said second gate insulator material; said assembly having a plurality of vias to contact said source and drain electrodes and a plurality of vias to contact said conductive oxide layer.
