1. A transistor for receiving at least one input signal, said transistor comprising:

  • an emitter electrode;

    a base electrode spaced apart from said emitter electrode such that at least a portion of said input signal may be applied across the emitter and base electrodes and, consequently, carriers are emitted from the emitter electrode toward the base electrode;

    a first tunneling structure disposed between said emitter and base electrodes and configured to serve as a transport of carriers between and to said emitter and base electrodes, said first tunneling structure including at least a first amorphous insulating layer and a different, second insulating layer disposed directly adjacent to and configured to cooperate with said first amorphous insulating layer such that the transport of carriers includes, at least in part, transport by tunneling;

    a collector electrode spaced apart from said base electrode; and

    a second tunneling structure disposed between said base and collector electrodes and configured to serve as a transport, between said base and collector electrodes, of at least a portion of said carriers emitted from said emitter electrode by ballistic transport such that the portion of the carriers is collectable at said collector electrode.
