Abstract: | Optical absorption spectra of tungsten diselenide (WSe2) single crystals subjected to different values of pressure (0, 2, 4 and 6 GPa) were obtained in the spectral range 700–1450 nm with the help of a UV–VIS–NIR spectrophotometer. The spectra were thoroughly analyzed in the absorption edge region for obtaining direct as well as indirect band gaps in this material. The high temperature resistivity and thermoelectric power on WSe2 single crystals at various pressures were also studied. The results and their implications are discussed in the article. |
