Transport spectroscopy and hybrid devices of transition metal dichalcogenide nanotubes

准二维平面过渡金属二硫族化合物（TMDCs）的研究引起了各方面的广泛关注。然而，人们对TMDC纳米管的低温输运特性知之甚少。据申请人所知，除了我们自己最近的一篇文章[doi:10.1002/pssr]。[201900251]关于库仑封锁和低温输运谱的研究尚无相关文献；在强离子掺杂下，纳米管的本征超导性得到了初步的研究成果。在这个项目中，我们将从二硫化钼开始，研究不同纳米管材料的半导体和超导特性。利用门定义电位和防止离子掺杂的局部氧化层，我们将设计在同一准一维纳米管中结合正常导电段和本质超导段的新型器件。由于已知TMDCs中存在强自旋轨道相互作用，这为拓扑超导和马约拉纳零模式开辟了前景。

Research on quasi-two dimensional, planar transition metal dichalcogenides (TMDCs) is attracting significant attention in every respect. However, not much is known on the low temperature transport properties of TMDC nanotubes. To the best of the applicant's knowledge, apart from our own recent article [doi:10.1002/pssr.201900251] no publications exist so far on Coulomb blockade and low temperature transport spectroscopy; first works in literature show highly promising results on intrinsic superconductivity of the nanotubes at strong ionic doping. In this project, we will investigate semiconducting and superconducting properties of different nanotube materials, starting with MoS2. Using gate-defined potentials and local oxide layers preventing ionic doping, we shall then design novel devices which combine normal-conducting and intrinsically superconducting segments within the same quasi-one dimensional nanotube. Since strong spin-orbit interaction is known to be present in TMDCs, this opens up perspectives towards topological superconductivity and Majorana zero modes.
