TaSe₂ Crystals

TaSe₂ (2H Phase) Crystals (Tantalum Diselenide) TaSe₂ (Tantalum Diselenide, 2H phase) is a layered transition metal dichalcogenide (TMD) with a hexagonal crystal structure. It exhibits metallic conductivity, strong electron correlation effects, charge density wave (CDW) transitions, and potential superconducting behavior at low temperatures. These properties make TaSe₂ a promising material for applications in nanoelectronics, superconductivity research, quantum materials, and 2D material studies. Our TaSe₂ (2H phase) crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and precise stoichiometry.
