Vanadium dichalcogenides have attracted increasing interests for the charge density wave phenomena and possible ferromagnetism. Here, we report on the multiphase behavior and gap opening in monolayer VTe 2 grown by molecular beam epitaxy. Scanning tunneling microscopy (STM) and spectroscopy study re...
