摘要：

We report on the generation of two-dimensional hole gas (2DHG) with robust stability at the interface of c-BN/diamond upon proper interface engineering without the requirement of hydrogen on diamond. The areal density of the 2DHG is as high as 9.85 x 10(12) cm(-2), and the hole mobility is as high as 924 cm(2)V(-1) s(-1). The intrinsic electron-deficiency nature of the interfacial carbon-boron bonds and the directional charge transfer due to the type-II band alignment are indispensable factors that synergistically lead to the formation of 2DHG.
