Effect of impurities on the thermal efficiency of a short-circuited generator

An analysis is made of the possibility of increasing the thermal efficiency Z_sh of a short-circuited anisotropic generator by doping with impurities and by choosing an optimum angular orientation. In an illustration it is shown that doping leads to an increase in Z_sh far beyond the value for an ordinary anisotropic generator. The calculated results are confirmed experimentally in a study of CdSb crystals doped with a silver acceptor impurity.Translated from Izvestiya VUZ. Fizika, No. 8, pp. 7–11, August, 1970.
