semiconductor· Pb0.7Ge0.3Te
Pb₀.₇Ge₀.₃Te is a lead-germanium-tellurium ternary semiconductor alloy belonging to the IV-VI narrow-bandgap family, engineered to tune electronic and thermal properties between binary PbTe and GeTe compounds. This material is primarily investigated for thermoelectric energy conversion applications where the bandgap engineering and phonon scattering control enable efficient direct heat-to-electricity conversion, particularly in mid-temperature regimes (200–500 K); it is also explored for infrared detection and sensing where its tunable bandgap and carrier mobility are advantageous compared to single-binary alternatives.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
