CONCENTRATION OF CARRIERS ON THE OPERATING
REGIMES OF A THERMOELECTRIC ARM

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.
