PdSe2 (Palladium Diselenide)

PdSe2 is a semiconductor 2D material having a bandgap ranging from 0eV to ~1.3eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. To buy PdSe2 crystals please click here.

The PdSe2 crystals produced at HQ Graphene have a typical lateral size of ~0.1-0.3 cm, hexagonal shaped and have a metallic appearance. More information about the PdSe2 crystals we sell can be found below.
