Overview

Titanium diselenide is a Group IV transition metal dichalcogenide (TMDC) exhibiting characteristic charge-density-wave (CDW) behavior. TiSe₂ has a layered 1T crystal structure with octahedral coordination, belonging to space group P-3m1 (point group D₃d), with adjacent layers held together by van der Waals interactions. Bulk 1T-TiSe₂ undergoes a charge-density-wave phase transition at approximately 200 K, forming a commensurate 2 × 2 × 2 CDW state. Under conditions such as high pressure or copper intercalation, CDW order can be suppressed, and superconductivity may emerge.
