Lattice thermal conductance and the ZT value. Calculated lattice thermal conductance (red) and optimized ZT value (blue) at 800 K for the (10,0) tube, where the 12C atoms are substituted by 13C atoms with different concentrations. Note that the results are given with respect to those of the pure 12C tube.
