Charge density waves in transition metal dichalcogenides have been intensively studied for their close correlation with Mott insulator, charge-transfer insulator, and superconductor. VTe2 monolayer recently comes into sight because of its prominent electron correlations and the mysterious origin of CDW orders. As a metal of more than one type of charge density waves, it involves complicated electron-electron and electronphonon interactions. Through a scanning tunneling microscopy study, we observed triple-Q π Γ π and single-Q π Γ π modulations with significant charge and orbital separation. The triple-Q π Γ π order arises strongly from the p-d hybridized states, resulting in a charge distribution in agreement with the V-atom clustering model. Associated with a lower Fermi level, the local single-Q π Γ π electronic pattern is generated with the p-d hybridized states remaining π Γ π ordered. In the spectroscopic study, orbital-and atomic-selective chargedensity-wave gaps with the size up to ~πππ πππ½ were resolved on the atomic scale.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citationsβcitations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
