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 widely studied in the fields of condensed matter physics, superconductivity, nanoelectronics, and energy storage due to its unique electronic and structural properties. Our TiSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and precise stoichiometry.
