Spin-valley coupling enhanced high-TC ferromagnetism in a non-van der Waals monolayer Cr2Se3 on graphene
Fabrication and characterization of ML Cr2Se3
First, we present fabrication and characterization of a ML Cr2Se3 film. Since Cr chalcogenides are stabilized with a few different chemical compositions such as CrSe2 (12…
