Emergence of Strain Induced Two Dimensional Metallic State in ReS2
We present a highly versatile system ReS2, which transforms from a semiconductor to a two dimensional metal under uni-axial compressive strain along ‘a’ direction in both bulk and monolayer. The 2D nature is realised from highly flat Fermi surfaces and anisotropic transport properties. Moreover the layer independent electronic structure properties are revisited and thermoelectric properties of ReS2 in bulk, monolayer and bilayer forms reveal the competing thermoelectric (TE) coefficients in each form. The in-plane power-factor shows an enhancement over ‘c’-axis value as a function of strain, which i...
