Due to its intrinsic two dimensional nature, planar MoS2 is at the center of manifold research efforts. Previous work has shown that MoS2 exhibits superconducting properties in single and multi layer flakes when increasing its charge density by heavily doping the MoS2 surface using a liquid-ion gate [1-3].
Clean and defect-free MoS2 nanotubes, as grown via chemical transport reaction [4,5], should provide an even better test bed for the interplay of a tubular geometry and Ising superconductivity. In addition, with ionic doping mostly affecting the outermost shell of a multi-wall nanotube, the material system lends itself intrinsically for core-shell semiconductor/superconductor hybrid structures at strong spin-orbin interaction. Here, we present our ongoing work towards this objective [6,7].
