Abstract:
1. A transistor device comprising source electrode and drain electrodes in different electrically conductive layers, a channel layer structure between said electrically conductive layers, and a gate on insulator structure attached to one of the source or drain electrodes with the insulator separating between the gate electrode and said one of the source and drain electrodes, wherein: said one of the source and drain electrodes is patterned, the pattern being in the form of spaced-apart perforations, such that each perforation is surrounded by the electrode layer material thereby providing discontinuity of electric conductivity within the electrode layer; and material compositions of the source electrode layer and channel are selected so as to create a barrier to charge injection into the channel thereby suppressing direct injection of charge from the source electrode to the drain electrode.
