Abstract
A field effect device includes a source electrode, a drain electrode spaced laterally apart from the source electrode, a channel formed between the source electrode and the drain electrode, and a gate electrode separated from the channel by an insulating layer. The channel includes a switching material that is reversibly switchable between a lower conductivity state and a higher conductivity state by at least one of: (i) application of a predetermined voltage between the source electrode and the drain electrode or between the gate electrode and at least one of the source electrode and the drain electrode, (ii) application of a voltage or a current to the switching material in the channel, and (iii) application of at least one of heat and light. Each of the conductivity states is persistent without the need for a sustaining excitation signal including an electrical field, heat and/or light applied to the device.
