Abstract

The parameters, Qs and Qk, were first introduced by Tuomi (1962, 1964) from research contracted to The Franklin Institute. They were named Qs=quality with respect to Seebeck and Qk=quality with respect to Kappa (thermal conductivity) (Tuomi 1983). The present author has used these parameters extensively, plus specimen test data from a single test point, to forecast the thermoelectric (TE) parameter temperature dependence, thereby proving the key information needed to design and optimize TE devices whenever only a single test point is available
