Abstract

We report on the experimental results of a new bidirectional bistability switching device using GaAs double triangular barrier structures prepared by molecular beam epitaxy. Bidirectional switching has been predicted experimentally in n+-n--δ(p+)-n --p+-n--δ(p+)-n --n+ structure. The significant S-shaped negative differential resistance characteristics are obtained due to the voltage-induced avalanche breakdown and potential barrier redistribution. A large on/off voltage ratio of ∼ 6.5 is observed in either direction of two-state at room temperature. In addition, the device can be expected to operate as a three-terminal triggered triac.
