  • Abstract
    A novel tunnel diode is proposed. Modulation doping is used to define a two dimensional electron or hole gas on either side of a p-n junction tunnelling barrier. The additional parameter of doping spike separation enables a wide range of I-V characteristics to be selected. This leads to a decoupling of the current peak and corresponding voltage. Improvements in current density and speed are predicted.
