摘要:

我们在这封信中报告的实验结果,证实了二维性质的电子系统在单层InN量子阱嵌入GAN的障碍。在这些InN量子阱中的二维电子系统(2DES)的电子密度和迁移率分别为5 × 10 ^{15} cm^{-2}和420 cm ^2/Vs。此外,2DES的对角电阻在很宽的温度范围内几乎没有温度依赖性,这表明了2DES的拓扑性质。

英文摘要:

We report in this letter experimental results that confirm the two-dimensional nature of the electron systems in monolayer InN quantum wells embedded in GaN barriers. The electron density and mobility of the two-dimensional electron system (2DES) in these InN quantum wells are 5x10^{15} cm^{-2} and 420 cm^2/Vs, respectively. Moreover, the diagonal resistance of the 2DES shows virtually no temperature dependence in a wide temperature range, indicating the topological nature of the 2DES.
