Experimental and theoretical field dependences of the thermopower of Pb1-xSnxTe

Experimental studies of transport phenomena in Pb1-xSnxTe provide the most complete information on the kinetics and energy spectrum of charge carriers over a wide range of charge carrier concentration, impurities, and temperature. Experimental field dependences of the thermopower of Pb1-xSnxTe with...
