How does the 0.18 eV direct band gap and 500 cm²/(V·s) electron mobility of Atomfair SnTe powder influence its performance in infrared detector research?
The direct band gap of 0.18 eV positions SnTe for detection of mid-infrared radiation (approximately 6.9 μm cutoff), while the electron mobility of 500 cm²/(V·s) supports efficient charge carrier transport. These properties, combined with the rock-salt cubic crystal structure, make the powder suitable for narrow-bandgap semiconductor and infrared-detector materials research as stated in the product's application scope.
What is the crystal structure and density of this SnTe powder, and what implications do they have for heterostructure device integration?
The powder exhibits a rock-salt cubic (cF8) crystal structure with a density of 6.445 g/cm³ and a melting point of 790 °C. The rock-salt structure is compatible with common IV-VI semiconductor substrates used in epitaxial growth for infrared detector and thermoelectric devices, facilitating integration into heterostructures without excessive lattice mismatch.
What particle size specification does the Atomfair SnTe powder have, and how does it affect thin-film deposition processing?
The powder is specified as -160 mesh, equivalent to -150 μm average particle size (APS). This fine particle size ensures uniform dispersion and consistent packing density when preparing pressed targets for sputtering or thermal evaporation, which is critical for achieving reproducible thin-film thickness and composition in narrow-bandgap semiconductor research.
