What is the band gap of Atomfair Antimony Telluride (Sb2Te3) powder and how does it influence its optoelectronic applications?
The band gap is 0.21 eV. This narrow band gap makes the material suitable for infrared photodetection and thermoelectric applications where low-energy photon absorption or charge carrier generation is required. The rhombohedral hR15 crystal structure further supports its anisotropic transport properties.
How does the -160 mesh particle size specification affect the processing of this Sb2Te3 powder into thermoelectric devices?
The -160 mesh particle size ensures a fine, uniform powder (particles smaller than 100 microns) that facilitates homogeneous mixing, pressing, and sintering for bulk thermoelectric elements or thin film deposition. This is critical for achieving consistent thermoelectric performance in cooling or power-generation modules.
What documentation is available to support safe handling of this high-purity Sb2Te3 powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation of purity and handling guidelines. Standard laboratory precautions for powdered heavy metal chalcogenides should be observed, including use of fume hoods, gloves, and eye protection.
Atomfair Antimony Telluride powder (99.999%, -160 mesh) features a narrow band gap of 0.21 eV and low thermal conductivity of 1.65 W/(m·K) at 308 K, supporting thermoelectric and optoelectronic research, though the high melting point of 620 °C necessitates specialized high-temperature processing equipment.
Positive
- High Purity (99.999%): The 5N purity level minimizes elemental contamination, critical for reproducible semiconductor and thermoelectric research.
- Low Thermal Conductivity: A thermal conductivity of 1.65 W/(m·K) at 308 K enhances thermoelectric performance by reducing heat loss across the material.
Trade-offs
- Narrow Band Gap (0.21 eV): The 0.21 eV band gap confines optoelectronic sensitivity to the far-infrared spectrum, limiting applicability in visible or near-IR devices.
- High Melting Point (620 °C): The elevated melting point requires specialized high-temperature processing equipment, increasing infrastructure demands for thin-film deposition or bulk sintering.
