The study demonstrates the presence of charge density wave state and possible coexistence of topological nontriviality and electron correlation in 1T-ZrTe2 monolayers. It provides a two-dimensional platform for exploring many body effects in topological nontrivial materials.
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.
