What is the typical particle size of Atomfair SnTe powder and how does it affect its use in semiconductor research?
The powder is supplied as -160 mesh with an average particle size of -150 microns (APS). This particle size is suitable for solid-state synthesis, evaporation, and further grinding for thin-film deposition, but may require additional processing for direct use in nanostructured devices.
What is the direct band gap of SnTe and what photodetector wavelength range does it cover?
The direct band gap is 0.18 eV, corresponding to an absorption edge of approximately 6.9 μm, which falls in the mid-infrared region. This makes SnTe relevant for infrared-detector materials research as stated in the product description.
What safety documentation is available for Atomfair SnTe powder and what handling precautions are recommended?
A Safety Data Sheet (SDS) and Certificate of Analysis (COA) can be provided upon request for batch-specific information. Since SnTe contains tellurium, which is toxic, standard laboratory protocols for handling heavy metal powders, including use of fume hoods and personal protective equipment, are recommended.
Atomfair Tin Telluride (SnTe) Powder at 99.99% purity and -160 mesh particle size provides a direct band gap of 0.18 eV and rock-salt cubic structure, making it well-suited for narrow-bandgap semiconductor and infrared-detector materials research. The high electron mobility (500 cm²/V·s) supports device-oriented studies.
Positive
- High Purity (99.99%): The 99.99% purity level minimizes contaminant interference, critical for reproducible semiconductor and infrared-detector research.
- Narrow Direct Band Gap (0.18 eV): The 0.18 eV direct band gap makes this material suitable for infrared detection and thermoelectric applications, enabling studies in the mid- to far-infrared range.
Trade-offs
- Fixed Particle Size (-160 Mesh): The powder is supplied at -160 mesh (up to 150 μm), which may require additional milling or classification for applications demanding finer particle sizes or uniform thin-film deposition.
