Advances in optimizing thermoelectric material efficiency have seen a\nparallel activity in theoretical and computational advances. In the current\nwork, it is shown that the calculation of exact Fermi-Dirac integrals enables\nthe generalization of the Wiedemann-Franz law (WF) to optimize the\ndimensionless thermoelectric figure of merit ZT. This is done by optimizing the\nSeebeck coefficient, the electrical conductivity and the thermal conductivity.\nIn the calculation of the thermal conductivity, both electronic and phononic\ncontributions are included. The solutions provide insight into the relevant\nparameter space including the physical significance of complex solutions and\ntheir dependence on the scattering parameter r and the reduced chemical\npotential.\n
