We present a new tunneling transistor based on a 2D black phosphorus and 3D indium arsenide heterojunction with a broken-gap band alignment. The observed negative differential resistance and negative transconductance behaviors can be attributed to the interband tunneling.

Spin Filtering

The transport properties of CrI3/h-BN/n·CrI3 (n = 1, 2, 3, 4) MTJs under positive bias voltages exhibit an interesting odd-even effect. Significant tunneling magnetoresistance, a perfect spin filtering effect and remarkable negative differential resistance were obtained.

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.
