OF WEAKLY DEGENERATE CARRIERS ON THE EFFICIENCY 
OF AN ARM OF A THERMOCOUPLE

The one-dimensional boundary problem on determination 
of a stationary temperature field in an adiabatically isolated one-dimensional 
arm of a thermocouple has been numerically solved. Calculations were 
carried out for two regimes of operation of the thermocouple, one 
which was characterized by a maximum temperature drop and the other 
by a maximum refrigerating capacity. The method of quantum statistics 
of carriers was used in the calculations. Homogeneous and inhomogeneous 
arms with different carrier-concentration distributions were considered. 
It is shown that a linear distribution cannot be considered as optimum.
