MoS₂ Crystals

Description

MoS₂ Crystals

MoS₂ is a layered transition metal dichalcogenide (TMD) known for its outstanding electronic, optical, and catalytic properties. It features a tunable bandgap that transitions from an indirect (~1.2 eV) in bulk to a direct bandgap (~1.8 eV) in monolayer form, making it ideal for applications in optoelectronics, nanoelectronics, and energy conversion. Our medium-area MoS₂ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, excellent crystallinity, and uniform large-area domains suitable for research and industrial applications.
