Charge density wave states in phase-engineered monolayer VTe2
文献摘要：
Charge density wave(CDW)strongly affects the electronic properties of two-dimensional(2D)materials and can be tuned by phase engineering.Among 2D transitional metal dichalcogenides(TMDs),VTe2 was predicted to require small energy for its phase transition and shows unexpected CDW states in its T-phase.However,the CDW state of H-VTe2 has been barely reported.Here,we investigate the CDW states in monolayer(ML)H-VTe2,induced by phase-engineering from T-phase VTe2.The phase transition between T-and H-VTe2 is revealed with x-ray photoelectron spectroscopy(XPS)and scanning transmission electron microscopy(STEM)measurements.For H-VTe2,scanning tunneling microscope(STM)and low-energy electron diffraction(LEED)results show a robust 2√3×2√3 CDW superlattice with a transition temper-ature above 450 K.Our findings provide a promising way for manipulating the CDWs in 2D materials and show great potential in its application of nanoelectronics.
