1. A hot electron transistor adapted 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, electrons 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 electrons between and to said emitter and base electrodes, said first tunneling structure including at least a first insulating layer such that the transport of electrons includes, at least in part, transport by means of 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 electrons emitted from said emitter electrode by means of ballistic transport such that said portion of the electrons is collectable at said collector electrode, wherein at least a selected one of said base electrode and said collector electrode is formed, at least in part, of a semi-metal.
