Efficiencies with optimized transmission functions. (a) Optimal values of the thermoelectric conversion efficiency for rectangular and Lorentz shaped transmission functions, plotted as a function of \(G_{th,loss}\). (b) The underlying optimized transmission functions.This plot is temperature invariant when choosing units of \(k_B T\) and the (electrical) thermal conductance quantum36 \(G_{th,0}=\frac{2\pi ^2k_B^2T}{3h}\) (left and lower scale). The right and upper scale denominate values at room temperature (T = 300K).
