ZrSe2 (Zirconium Diselenide)

ZrSe2 Zirconium Diselenide ZrSe2 is a semiconductor with a band gap of ~1 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Zirconium Diselenide belongs to the group-IV transition metal dichalcogenides (TMDC). To buy ZrSe2 crystals please click here.
