Optimized thermoelectric properties of p-type PbTe 0.88 Ag 0.12 through metallic transition and investigation of its time- and temperature-dependent oxidation process

Key Points

• To investigate the effects of silver doping on the thermoelectric properties and oxidation behavior of PbTe.
• Evaluated the thermoelectric properties of p-type PbTe doped with 12% silver.
• Analyzed oxidation stability in different temperature conditions.
• Compared performance of silver-doped PbTe with pure PbTe.
• Silver doping significantly improves oxidation stability compared to pure PbTe.
• Doped PbTe maintains high thermoelectric performance alongside reduced oxidation rates.
