随着最近几年单层二硫化钼实验方面的令人振奋的发展，对单层二硫化钼相关电学和光学性质的研究已成为目前理论和实验研究领域的一个研究热点。本项目旨在揭示自旋轨道耦合效应、自旋-谷耦合和单层二硫化钼基超导异质结内 Andreev 反射（Retro- 和 Specular-）、Crossed Andreev 反射（Retro- 和 Specular-）以及 Andreev 束缚态之间的相互作用关系及其物理本质。与此同时澄清相关超导异质结的量子输运特性及其调制规律，为单层二硫化钼基谷超导量子器件的设计提供理论指导。由于超导量子器件具有灵敏度高、能耗低和响应速度快等一系列特点，使得该类器件具有广阔的应用前景。此外，我们可以预期对单层二硫化钼类材料所特有的自旋-谷耦合的研究将得到一系列全新的谷相关量子现象。因此本项目的研究不但具有潜在的应用价值，而且具有重要的理论研究意义。

Recently, from theoretical and experimental point of view, great interest has been aroused in research on the excellent electrical and optical properties of monolayer molybdenum disulfide due to its exciting developments in experiments. In the project, the physical phenomena of Andreev reflection(Retro- and Specular-), crossed Andreev reflection(Retro- and Specular-), and Andreev bound state under the influence of spin-valley coupling and spin-orbit coupling through monolayer molybdenum disulfide based superconducting heterojunctions are considered. Subsequently the physical essences of those intriguing phenomena will be revealed. Meanwhile, the transport properties of those structures will be investigated which provide a crucial reference to realize valley superconducting quantum devices based on monolayer molybdenum disulfide. Quantum devices with superconductors lead to many peculiar properties, such as higher sensitivity, lower energy cost, fast response speed, etc, which bring us a wider prospective application in valleyelectronics based on monolayer molybdenum disulfide. Spin-valley coupling due to inversion symmetry breaking and strong spin-orbit coupling which only live in monolayer molybdenum disulfide and other group-VI transitionmetal dichalcogenides should therefore yield a series of intriguing valley resolved quantum phenomena not known from earlier studies. Therefore, this project not only has potential application value, also possesses significant theoretical research significance.
