SnSe2 (Tin Diselenide)

SnSe2 Tin Diselenide SnSe2 is a semiconductor having an indirect bandgap. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Tin Diselenide belongs to the group-14 post-transition metal dichalcogenides. To buy SnSe2 crystals please click here.
