Unconventional Superconductivity in monolayer Transition Metal Dichalcogenides via proximity

ORAL

Abstract

Single layer Transition Metal Dichalcogenides (TMDCs) provide a unique platform to study the interplay of spin-orbit coupling, topology and electron-electron interactions. In addition, the ultrathin 2D geometry allows for proximal coupling to other materials particularly magnets and superconductors. In this talk we report on the nature of the induced superconducting state when coupled to a conventional superconductor. Going beyond the tunneling model we solve a self-consistent Bogoliubov-De Gennes equations for the heterostructure to establish the nature of the paired state. Introducing a third device component, a ferromagnet such as Chromium tri-Iodide, breaks time reversal allowing access to the topologically nontrivial electronic states of the TMDC. Modifications of the induced phase and conditions for realizing topological superconductivity will be discussed.
