Room temperature reflectivity and thermoreflectance spectra of 1T VSe2

Abstract
Room temperature reflectivity and thermoreflectance measurements of 1T VSe2 below and above the charge density wave (CDW) transition temperature have been carried out. A noticeable change in the thermo-optical response at about 108K has been detected around 1.65 eV which seems to be due to the CDW onset. No evidence has been found of the commensurate CDW transition at 70K.
