Charge Density Wave Proximity Effect in Graphene on 1T-TaS<sub>2</sub>

ORAL

Abstract

Due to the non-local nature of electrons in materials, ordered states within a correlated material cannot abruptly change to another type of ordering at the interface with another material. As a result, correlated electron states persist into the normal metal (and vice versa). Several well-known examples of contact proximity effects have led to observations of magnetism, spin-orbit effects, and superconductivity induced in normal metals by contact with a correlated material. Here, we provide microscopic evidence, by means of scanning tunneling microscopy/spectroscopy and modelling based on density functional theory, of a novel proximity induced charge density wave in graphene placed on 1T-TaS2.
