Crystal Overview
We supply large-area, high-purity molybdenum disulfide (MoS₂) single crystals. These crystals exhibit superior structural and electronic quality and are delivered exfoliation-ready for immediate use in research and device fabrication.
The MoS₂ single crystals are synthesized using Chemical Vapor Transport (CVT) / Direct Vapor Transport (DVT) techniques, with growth parameters carefully optimized to ensure precise control over crystal phase, stoichiometry, and defect density. Post-growth annealing and refinement procedures further enhance structural order and phase purity.
Our crystals exhibit the following key properties:
- High crystallinity and phase purity: Verified by X-ray diffraction (XRD) and Raman spectroscopy, confirming the 2H-MoS₂ hexagonal structure with excellent in-plane alignment.
- Exfoliation-ready layered structure: The material cleaves cleanly into thin monolayers or few-layer flakes with atomically smooth surfaces, ideal for two-dimensional materials research.
- Well-defined electronic structure: Bulk crystals exhibit an indirect band gap of ~1.2 eV, while monolayers show a direct band gap of ~1.8-1.9 eV, making them highly suitable for electronic, optoelectronic, and photonic applications.
- Controlled phase composition: Our synthesis ensures phase-pure 2H-MoS₂, avoiding metallic 1T phases, and provides reproducible electronic and optical properties.
- Exceptional chemical and thermal stability: MoS₂’s layered structure ensures robustness under device fabrication and operation conditions.
With their large size, high crystallinity, and well-defined electronic properties, these MoS₂ single crystals provide an ideal platform for fundamental studies, next-generation electronic devices, and high-performance optoelectronic applications
