A polymer-based or silicon-based accumulation type, depletion mode field
effect transistor, suitable as a driver for load. Optionally, the load is
another accumulation type, depletion mode field effect transistor. The
transistor may be of the TFT type, either lateral or vertical. Optionally,
it may have Schottky diode contacts to source and drain electrodes,
possibly with a reverse biased Schottky junction, or it may have a
negatively charged gate dielectric.
