Problem

A candidate thermoelectric material at T=320 KT=320\,\mathrm{K} has measured properties S=150 μV K−1S=150\,\mu\mathrm{V\,K^{-1}}, σ=8.0×104 S m−1\sigma=8.0\times10^{4}\,\mathrm{S\,m^{-1}} and total thermal conductivity κ=1.8 W m−1K−1\kappa=1.8\,\mathrm{W\,m^{-1}K^{-1}}. Calculate its figure of merit ZTZT at this temperature.
