TiTe2 (Titanium Ditelluride)

TiTe2 Titanium Ditelluride TiTe2 is a semimetal. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. The semi-metal Titanium Ditelluride belongs to the group-VI transition metal dichalcogenides (TMDC). To buy TiTe2 crystals please click here.
