VSe₂ Crystals

VSe₂ Crystals

VSe₂ (Vanadium Diselenide) is a layered transition metal dichalcogenide (TMD) with a van der Waals structure, exhibiting metallic conductivity, electron correlation effects, and charge density wave (CDW) behavior. It is studied in spintronics, superconductivity research, nanoelectronics, and energy storage applications due to its electronic and magnetic properties. VSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
