Electronic structure of epitaxially-grown monolayer 1T’-MoTe<sub>2</sub>

ORAL

Abstract

We have investigated the electronic structure of monolayer 1T’-MoTe2 grown by molecular beam epitaxy on bilayer graphene substrate. Angle-resolved photoemission measurements found the spin-orbit-coupling induced breaking of the band degeneracy points between the valence and conduction bands. The strength of spin-orbit-coupling is found to be insufficient to open a band gap, which makes monolayer 1T’-MoTe2 on bilayer graphene a semimetal.
