MoS₂ Crystals

MoS₂ Crystals

MoS₂ is a layered transition metal dichalcogenide (TMD) with electronic, optical, and catalytic properties. It features a variable bandgap that transitions from an indirect (~1.2 eV) in bulk to a direct bandgap (~1.8 eV) in monolayer form, supporting applications in optoelectronics, nanoelectronics, and energy conversion. MoS₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
