TiSe₂ Crystals

TiSe₂ Crystals

TiSe₂ (Titanium Diselenide) is a layered transition metal dichalcogenide (TMD) with a van der Waals structure, exhibiting metallic conductivity, charge density wave (CDW) transitions, and potential superconducting behavior at low temperatures. It is investigated in the fields of condensed matter physics, superconductivity, nanoelectronics, and energy storage due to its electronic and structural properties. TiSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
