Observation of pressure induced charge density wave order and eightfold structure in bulk VSe2

Abstract Pressure-induced charge density wave (CDW) state can overcome the low-temperature limitation for practical application, thus seeking its traces in experiments is of great importance. Herein, we provide spectroscopic evidence for the emergence of room temperature CDW order in the narrow pres...
