ReSe2 (Rhenium Diselenide)

ReSe2 Rhenium Diselenide ReSe2 is a semiconductor (~1.1 eV). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Rhenium Diselenide belongs to the group-VII transition metal dichalcogenides (TMDC). To buy ReSe2 crystals please click here.

The ReSe2 crystals produced at HQ Graphene have triangular shapes and a metallic appearance. We produce n-type ReSe2, having a typical charge carrier density of ~10¹⁶cm^-3 at room temperature. A selection of peer review publications on the ReSe2 crystals we sell can be found below.
