PtSe2 (Platina Diselenide)

PtSe2 Platina Diselenide PtSe2 is a semimetal. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. The Platinum Diselenide semi-metal belongs to the group-X transition metal dichalcogenides (TMDC). To buy PtSe2 crystals please click here.

The PtSe2 crystals produced at HQ Graphene have a typical lateral size of ~0.2-0.3 cm, and have a metallic appearance. More information on the PtSe2 crystals that we sell can be found below.
