tunnel diode: see diode diode (dī`ōd), two-terminal electronic device that permits current flow predominantly in only one direction. ..... Click the link for more information. . tunnel diode [′tən·əl ‚dī‚ōd] (electronics) A heavily doped junction diode that has a negative resistance at very low voltage in the forward bias direction, due to quantum-mechanical tunneling, and a short circuit in the negative bias direction.

Interesting as the hydrogen atom and the microwave experiments are, a novel tunnel diode and devices like it are more likely to show up in practical applications,' notes Eric J. n+GaInP/p+GaAs tunnel diodes were fabricated for carbon kinetics. The sine qua non of a tunnel diode is an unusual behavior called negative differential conductivity, which means that for a particular range of increasing voltages (when applied across a diode's two terminals) there is a reduction in the current of electrons that tunnel through the energy barrier between the terminals. |
