Tungsten Disulfide WS2 99.995% ~10mm Crystal ATOMFAIR®

This WS2 layered crystal material at 99.995% purity and ~10mm size offers high phase-purity for fundamental 2D material exfoliation and device fabrication, but the fixed ~10mm crystal dimension and box packaging impose handling and integration constraints for users requiring larger-area substrates or controlled-environment storage.

Positive

• High purity 99.995%: The 99.995% purity minimizes extrinsic dopants and defects, critical for reproducible electronic transport and optical measurements in monolayer WS2 devices.
• Layered crystal form for exfoliation: Supplied as ~10mm silver-gray crystals, this form factor is directly suited for mechanical exfoliation to produce monolayer or few-layer flakes for 2D material research.

Trade-offs

• Fixed ~10mm crystal size: The ~10mm crystal dimension limits the maximum lateral flake area obtainable via exfoliation; users requiring larger-area continuous films must consider alternative synthesis routes.
• Box packaging without environmental control: Packaged in a box without specified inert atmosphere or vacuum sealing, the crystal surface may oxidize or adsorb contaminants during storage, requiring immediate handling in a glovebox for air-sensitive applications.
