Enhanced superconductivity in 2M-WS<sub>2</sub> through doping
ORAL
Abstract
A new member of transition metal dichalcogenide (TMD) family, 2M-WS2, has been recently discovered and shown to display superconductivity with a critical temperature (Tc) of 8.8 K, the highest Tc among superconducting TMDs at ambient pressure. Using first-principles calculations combined with the anisotropic Migdal-Eliashberg formalism, we explore how the superconducting properties of 2M-WS2 can be enhanced through doping. We find that compared to the parent compound the electron-phonon coupling can be increased by p-type doping, leading to an enhancement of the Tc up to 50%.
