title = "Growth of epitaxial quality SnS thin films on graphene",
abstract = "SnS van der Waals epitaxies (vdWEs) were grown by molecular beam epitaxy (MBE) on layered substrates such as graphene and mica. Photo-absorption measurements indicate an indirect bandgap of ∼1 eV and a direct bandgap of ∼1.25 eV. The technique leads to significant improvement in the crystallinity of the films compared to the samples deposited on convention crystalline semiconductors or soda lime glass. The absorption coefficient, α, is of the order of 104 cm-1 with sharp cutoff in energy indicating low concentration of bandgap states. Hole mobility of ∼81 cm2V-1s-1 was observed for SnS films on graphene/GaAs(100) substrates.",
