摘要

在这项工作中，我们使用iii -氮化物中的弹道量子输运来实现基于gan的隧道热电子晶体管的室温负差分电阻(NDR)。结果表明，双扫描特性可重复，峰谷比(PVCR)为7.2，峰值电流密度(PCD)约为143 A/cm2。这是在iii -氮化物器件中首次报道可重复室温负差分电阻。

Room temperature negative differential resistance in a GaN-based Tunneling Hot Electron Transistor

In this work, we use ballistic quantum transport in a III-nitride to realize room temperature negative differential resistance (NDR) in a GaN-based Tunneling Hot Electron Transistor. The results showed reproducible double-sweep characteristics, with peak-to-valley ratio (PVCR) of 7.2 and peak current density (PCD) about 143 A/cm2. This is the first report of repeatable room temperature negative differential resistance in a III-nitride device.
