Ag1-xPb18MTe20 — Thermal Conductivity

This plot shows the measurements carried out on AgPb18Te20 in the temperature range from 150°C to 370°C. The lattice conductivity can be calculated from the measured thermal conductivity. Here, the temperature dependence of the total thermal conductivity (λtot) and lattice thermal conductivity (λlatt) of AgPb18BiTe20 is demonstrated.

The inset depicts the temperature dependence of the lattice thermal conductivity of Ag1-xPb18BiTe20 (x = 0, 0.3), compared with the lattice thermal conductivity of AgPb18BiTe20 (presented in + symbol). (measurement with LFA 457 MicroFlash®)
