Abstract:
1. A geometric diode, comprising: a device body formed from an electrically conductive material having an equilibrium mobile charge density of at least 10 at least a pair of first and second electrodes defined on the device body such that the device body serves as an electrically conductive path between the first and second electrodes wherein the electrically conductive path is delimited by the device surface configuration and the device surface configuration is physically asymmetric with respect to a forward flow of current in a forward direction from the first electrode to the second electrode as compared to a reverse current flow in an reverse direction from the second electrode to the first electrode such that a magnitude of the current between the first electrode and the second electrode, as a function of a voltage between the pair of electrodes, is different in the forward direction from that in the reverse direction without a need for the formation of a depletion layer in the electrically conductive material to produce the difference in current magnitude.
