Abstract
ZrSe2 exhibits a pressure-induced gradual structural phase transition from hexagonal 1T phase to a monoclinic phase, which starts around 5.9 GPa and completes around 14.8 GPa. Anomalies found in high pressure Raman measurements indicate the presence of a possible electronic phase transition mediated by the differential strain produced inside the sample.
