What are the band-gap values of this MoS2 powder and why are they relevant to layered-semiconductor research?
The Atomfair MoS2 powder has a band gap of approximately 1.23 eV in bulk and 1.8 eV for a monolayer. These values are directly relevant to layered-semiconductor research because the monolayer value is significantly higher, and the product is supplied for layered-semiconductor materials research.
Is this 99.5% MoS2 powder intended for use in both dry-lubricant and semiconductor research applications?
Yes, the product is explicitly supplied for dry-lubricant and layered-semiconductor materials research. It is a defined MoS2 composition with CAS 1317-33-5, 99.5% purity, -1250 mesh, and appears as a black or lead-gray powder, supporting evaluation in both application areas.
What batch-specific documentation is available for this MoS2 powder?
A certificate of analysis (COA) and safety data sheet (SDS) can be provided upon request for batch-specific confirmation. Contact the technical sales team via inquiry@atomfair.com to request documentation for a specific lot.
Atomfair MoS2 powder (99.5% purity, -1250 mesh, CAS 1317-33-5) is assessed as a defined sulfide starting material for dry-lubricant and layered-semiconductor research. The reported bulk and monolayer band-gap values make it suitable for layer-dependent electronic studies, while users must account for its water insolubility and request documentation for batch-specific confirmation.
Positive
- 99.5% purity with defined CAS: Supplied at 99.5% purity and identified as molybdenum sulfide (MoS2, CAS 1317-33-5), providing a defined sulfide composition for dry-lubricant and layered-semiconductor research.
- Bulk and monolayer band-gap values: The reported band gap of approximately 1.23 eV in bulk and 1.8 eV for a monolayer offers a useful reference for evaluating layer-dependent electronic behavior in MoS2.
Trade-offs
- Insoluble in water: MoS2 powder is insoluble in water, so aqueous solution-based processing or dispersion routes are not viable with this material.
- Documentation only upon request: Batch-specific COA and SDS are not included by default and must be requested to confirm the exact characteristics of a supplied batch.
