MoWS₄ Crystals

MoWS₄ Crystals

MoWS₄ is a layered transition metal chalcogenide alloy that combines the properties of both MoS₂ and WS₂. This mixed-metal sulfide exhibits variable electronic, optical, and catalytic properties, depending on the Mo:W ratio, supporting applications in nanoelectronics, optoelectronics, energy storage, and catalysis. MoWS₄ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
