VSe₂ Crystals

VSe₂ Crystals

VSe₂ (Vanadium Diselenide) is a layered transition metal dichalcogenide (TMD) with a van der Waals structure, exhibiting metallic conductivity, strong electron correlation effects, and charge density wave (CDW) behavior. It has gained significant attention in spintronics, superconductivity research, nanoelectronics, and energy storage applications due to its unique electronic and magnetic properties. Our VSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and precise stoichiometry.
