We report pressure evolution of charge density wave (CDW) order and the emergence of superconductivity (SC) in 1T -VSe2 single crystal by studying resistance and magnetoresistance behavior under high pressure. With increasing quasihydrostatic pressure the CDW order enhances with its ordering temperature (∼100 K at ambient P) increasing marginally up to 5 GPa. At higher pressures, CDW-like resistance anomaly increases more rapidly with the characteristic temperature reaching ∼290 K at 14.2 GPa. Upon further increase of pressure, the resistance anomaly due to CDW order gets suppressed drastically with rapidly increased metallicity (as clearly evidenced from the increased RRR value) and superconductivity emerges at ∼15 GPa, with the onset critical temperature (Tc) ∼4 K. The pressure dependence of Tc is found negligible, different from an increase or a domeshaped behavior seen in isostructural layered diselenide superconductors. The high-pressure magnetoresistance and Hall measurements suggest successive electronic structural changes with Fermi surface modifications at 5 and ∼12 GPa.
