Abstract :
We have fabricated a novel type of interband resonant tunnel diode by MBE growth of a superlattice, each period of which consists of layers of GaSb, AlSb and InAs. The diode is designed to conduct in forward bias by resonant interband tunneling, so that the entire stack appears to be a short circuit. Reverse bias current is impeded by band gap blocking. The reverse breakdown voltage varies with the number of periods, with each period capable of blocking about 0.4 V. A four period diode conducts 5000 A/cm2 at less than 0.3 V of forward bias
