Electronic structure of monolayer 1T-CrTe<sub>2</sub> on bilayer graphene

ORAL

Abstract

We report the electronic structure of monolayer 1T-CrTe2 grown by molecular beam epitaxy on bilayer graphene substrate. Angle-resolved photoemission spectroscopy (ARPES) reveals electronic band structures consistent with the first-principles calculations, accompanied by an unconventional temperature evolution across the Curie temperature of 150 K. Our results suggest multiple exchange mechanisms, enhanced by the lattice distortion and the electron doping from the bilayer graphene substrate, need to be considered for a comprehensive understanding of the ferromagnetic transition in monolayer 1T-CrTe2.
