MoSe₂ Crystals

MoSe₂ Crystals

MoSe₂ (Molybdenum Diselenide) is a layered transition metal dichalcogenide (TMD) with a van der Waals structure. It exhibits a tunable bandgap, strong spin-orbit coupling, and excellent electronic and optoelectronic properties, making it highly suitable for applications in nanoelectronics, optoelectronics, spintronics, and 2D material research. Our MoSe₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, superior crystallinity, and well-controlled stoichiometry.
