First observation of switching behavior is reported in GaAs metal-insulator-p-n+structure, where the thin insulator is grown at low temperature by a liquid phase chemical-enhanced oxide (LPECO) with a thickness of 100 Å. A significant S-shaped negative differential resistance (NDR) is shown to occur that originates from the regenerative feedback in a tunnel metal/insulator/semiconductor (MIS) interface andp-n+junction. The influence of epitaxial doping concentration on the switching and holding voltages is investigated. The switching voltages are found to be decreased when increasing the epitaxial doping concentration, while the holding voltages are almost kept constant. A high turn-off/turn-on resistance ratio up to105has been obtained.

Good Agreement

The I-V curves in multi-quantum wells of different semiconductors are studied theoretically using the formalism of the transmission coefficient directly derived from Schrödinger equation. Al0.5Ga0.5As/GaAs double-barrier quantum well, Al0.29Ga0.71As/GaAs multi-quantum well, and AlSb/InAs double-barrier structure are calculated. The influences of well width, barrier width, temperature, Fermi energy on I-V characteristic curves are discussed in detail. Calculated results show that obvious negative differential resistance effects presented by our simulated I-V curves has a good agreement with previous experiments. Therefore, it can be a theoretical expectation to design experimentally high-quality semiconductor devices.
