Superconductivity in Few-Layer T_d-MoTe₂

Layered transition metal dichalcogenides have recently emerged as promising candidates to explore the interplay between symmetry and novel quantum properties. Among them, bulk T_d-MoTe₂ is a type-II Weyl semimetal with low symmetry and a superconductive phase below 120 mK. In the 2D limit, few-layer T_d-MoTe₂ may feature topological superconductivity and display other exotic superconducting properties. In this talk, I will discuss electronic properties of few-layer T_d-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.
