MoSe2 (2H phase) is a semiconductor having an indirect band gap of ~1.1 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. MoSe2 belongs to the group-VI transition metal dichalcogenides (TMDC). To buy MoSe2 crystals please click here.
The 2H phase Molybdenum Diselenide crystals produced at HQ Graphene have a typical lateral size of ~0.8-1 cm, are hexagonal shaped and have a metallic appearance. We produce both p-type and n-type MoSe2, having a typical charge carrier density of ~1015cm-3 at room temperature. A selection of peer review publications on the MoSe2 we sell can be found below.
