Superconductivity and Ferroelectricity Few-Layer T_d-MoTe₂

I will discuss how the influence of an electrostatic gate allows us to identify a unique superconducting state in bilayer T_d-MoTe₂ and its profound influence even when no change in the chemical potential is made. Our results indicate that superconductivity in bilayer T_d-MoTe₂ can be completely quenched by an electrostatic gate, and that the superconducting behavior is connected to Fermi surface nesting between electron and hole pockets. In addition, due to the noncentrosymmetric crystal structure of bilayer T_d-MoTe₂ ferroelectric behavior, as a result of interlayer sliding, is established. This behavior, concomitant with superconductivity, allows for the first investigations of how internal polarization might conflict with or enhance superconductivity in the two-dimensional limit.
