There has been growing interest in the study of crystalline 2D superconductors, especially those with low carrier densities with gate tunability. Recently, it is reported that monolayer 1T_d-MoTe₂ exhibits superconductivity with transition temperature of 8 K [1], much enhanced from the bulk whose T_c = 0.1 K [2], and higher than the isostructural monolayer 1T_d-WTe₂ with its T_c = 0.7 K [3,4]. Whereas monolayer MoTe₂ is inversion-symmetric, inversion-symmetry is broken in bilayer MoTe₂ due to the stacking arrangement, which can change the superconducting properties. Here we will report the quantum transport properties of bilayer and monolayer MoTe₂, for a better understanding of its superconductivity, and pursuing topologically non-trivial state in this platform.
