论文摘要
使用第一原理计算系统地研究了两种类型的侧向VS2 | MOS2异插的固有旋转依赖性转运性能，并设计了其各种具有新颖性能的纳米电视。横向VS2 | MOS2异质结二极管二极管具有完美的整流效果，并且有望适合Schottky Diodes的应用。对于A型设备，观察到一个较大的自旋偏振比，然后实现了纯自旋介导的电流。栅极电压显着调节其场效应晶体管（FET）的电流和整流比。另外，它们都对蓝光具有敏感的光响应，并且可以用作光电探测器和光伏设备。此外，当两个终端之间出现温度感激之情时，它们会产生有效的热驱动电流，这表明它们是潜在的热电材料。因此，横向VS2 | MOS2异质膜表现出多功能性质，并且在旋转，光电子和旋转热量量子方面具有各种潜在的应用。
The intrinsic spin-dependent transport properties of two types of lateral VS2|MoS2 heterojunctions are systematically investigated using first-principles calculations, and their various nanodevices with novel properties are designed. The lateral VS2|MoS2 heterojunction diodes show a perfect rectifying effect and are promising for the applications of Schottky diodes. A large spin-polarization ratio is observed for the A-type device and pure spin-mediated current is then realized. The gate voltage significantly tunes the current and rectification ratio of their field-effect transistors (FETs). In addition, they all have sensitive photoresponse to blue light, and could be used as photodetector and photovoltaic device. Moreover, they generate the effective thermally-driven current when a temperature gratitude appears between the two terminals, suggesting them as potential thermoelectric materials. Hence, the lateral VS2|MoS2 heterojunctions show a multifunctional nature and have various potential applications in spintronics, optoelectronics, and spin caloritronics.
