A simple time-dependent relation between the current and voltage pulse in a one-dimensional diode has been obtained. The relation is applicable to diodes in which the voltage or current pulse changes appreciably during the beam transit time across the diode gap. A simple application of the results to eliminating current transients in ion diodes is presented.

    Thermally stimulated resonant current peaks are observed in Al0.4Ga0.6As/GaAs triple barrier diodes. These current peaks are interpreted as resonant tunnelings from the first excited electron subband in the first well to the first excited subband and to the second excited subband in the second...
