(a) Comparison of the calculated lattice thermal conductivity κ ph versus temperature data for TaN and TaSb binaries. Vertical axis is in logarithmic scale. (b) The maximum estimated thermopower or Seebeck coefficient, and (c) maximum estimated thermoelectric figure of merit computed at 300 K and 800 K for the electronic doping case. Data from Ref. [42] is reused to produce this figure.
