This letter reports a recent experiment on resonant interband tunneling (RIT) diodes and the measured room temperature peak-to-valley (P/V) current ratio of 104:1 which represents the highest P/V ratio ever reported in any tunneling device. The RIT diode studied in this work consists of an InGaAs/InAlAs double-quantum well system embedded in a pn junction structure grown on InP.
Day et al. (Mon,) studied this question.
