Monolayer Structure and Properties

WS2 powder consists of nanoscale flakes with a single-layered hexagonal structure, resulting in unique electrical and optical characteristics. Its high mechanical strength and excellent dimensional stability make it suitable for state-of-the-art research and industrial applications. The monolayer architecture ensures minimal porosity and a smooth, layered surface, enhancing performance in demanding environments.

Storage and Handling Recommendations

To preserve the superfine quality, store WS2 powder in a cool, dry environment away from direct sunlight. The material is minimally sensitive to moisture and air, but exposure should still be limited to maintain purity and shelf life. Under recommended conditions, the product remains stable for up to 24 months. Always handle using appropriate safety measures to avoid contamination.

Applications Across Industries

Monolayer WS2 finds versatility in transistors, field-effect transistors (FETs), flexible electronics, batteries, lubrication, and various sensing devices. Its direct bandgap and strong mechanical properties drive innovative solutions in photodetectors and catalysis. Indian wholesalers, manufacturers, and suppliers offer WS2 for both research and production requirements, facilitating cutting-edge advancements countrywide.

FAQs of Monolayer Tungsten Disulfide Powder, WS2:

Q: How should Monolayer Tungsten Disulfide (WS2) Powder be stored to maintain its quality?

A: The powder should be stored in a cool, dry place, away from direct sunlight. Though it is only minimally sensitive to moisture and air, limiting exposure will help maintain its purity and shelf life, which is up to 24 months under recommended conditions.

Q: What is the process used to produce monolayer WS2 powder?

A: Monolayer WS2 powder is typically produced through chemical exfoliation or chemical vapor deposition (CVD). These methods ensure a single-layered, hexagonal structure with flakes averaging 0.55 microns in lateral size.

Q: Where is WS2 powder commonly used and what are its major applications?

A: WS2 powder is widely used in the electronics and optoelectronics industry, especially in transistors, FETs, flexible electronics, batteries, lubrication, sensing devices, photodetectors, and catalysis due to its advantageous properties.

Q: What benefits does WS2 offer in advanced electronic applications?

A: With a direct bandgap of approximately 2.1 eV and high mechanical strength, monolayer WS2 enables superior performance in transistors, photodetectors, and flexible electronics, allowing for miniaturization and increased device efficiency.

Q: When should WS2 powder replacement be considered during storage?

A: WS2 powder should be considered for replacement after its shelf life of 24 months, or if there are any visible changes in its physical appearance, indicating possible contamination or degradation.

Q: What safety measures are recommended when handling WS2 powder?

A: Users should avoid unnecessary exposure to moisture and air, handle the powder in a clean environment, and use suitable protective equipment such as gloves and masks to prevent contamination and ensure safe usage.

Q: Who supplies Monolayer WS2 in India, and in what forms can it be sourced?

A: WS2 powder is available in India through dealers, manufacturers, exporters, importers, retailers, suppliers, and wholesalers. It can be sourced in powder or monolayer nanosheet forms, tailored for various research and industrial needs.
