Superconductivity in Few-Layer T<sub>d</sub>-MoTe<sub>2</sub>

ORAL

Abstract

Layered transition metal dichalcogenides have recently emerged as promising candidates to explore the interplay between symmetry and novel quantum properties. Among them, bulk Td-MoTe2 is a type-II Weyl semimetal with low symmetry and a superconductive phase below 120 mK. In the 2D limit, few-layer Td-MoTe2 may feature topological superconductivity and display other exotic superconducting properties. In this talk, I will discuss electronic properties of few-layer Td-MoTe2, including an unusual gate dependence of the superconductivity that we have systematically characterized at multiple sample thicknesses. We supplement these intriguing transport results with optical measurements such as second harmonic generation.
