  • LOW VOLTAGE NANOSCALE VACUUM ELECTRONIC DEVICES
    Publication number: 20160196948
    Abstract: An electronic device including a first conducting layer, a second conducting layer, and an insulating layer provided between the conducting layers. At least one side wall extends from the first conducting layer to the second conducting layer and includes at least a portion of the first conducting layer, the second conducting layer and the insulating layer. A bias voltage is applied between the first and second conducting layers, wherein responsive to the bias voltage, a two dimensional electron system is induced at least in one of the first conducting layer and the second conducting layer, and wherein electrons from the two dimensional electron system are emitted from the side wall side wall as a result of Coulombic repulsion and travel in air from the one of the first conducting layer and the second conducting layer to the other of the first conducting layer and the second conducting layer.
    Type: Application
