Coexistence of the charge density wave state and linearly dispersed energy band in 1T-ZrTe2 monolayer

Interplay between the topological properties and electron correlations in quantum materials can induce exotic phenomena. In this study, we grew the 1T-ZrTe2 monolayers on the bilayer graphene/SiC substrate by using molecular beam epitaxy. Through scanning tunneling microscopy/spectroscopy characterizations, we demonstrate that the 1T-ZrTe2 monolayer hosts the charge density wave state, as well as a linear dispersion energy band near Fermi energy, thereby implying the possible coexistence of the topological nontriviality and electron correlation. This work provides a two-dimensional platform for exploring the many body effect in topological nontrivial materials.
