INFLUENCE OF THE LINEARLY DISTRIBUTED CONCENTRATION OF CARRIERS ON THE OPERATING REGIMES OF A THERMOELECTRIC ARMO. I. Markov UDC 621.362.1 A numerical solution of the boundary-value problem on calculation of the temperature field in a one-dimensional adiabatically insulated inhomogeneous thermoelectric arm has been obtained. The concentration gradient of nondegenerate carriers has been optimized, which enables one to substantially increase the thermo- electric Q-factor of the arm. The calculations have been carried out for two operating regimes - the regime of maximum temperature difference and that of maximum refrigerating capacity. The possible limits of optimization of the concentration gradient of charge carriers have been established. Orel State University, Orel, Russia; email: Markov@e-mail.ru.
