A detailed analysis of the influence of thermal nonequilibrium on transport in semiconductors was carried out. It is shown that the transport of heat and electricity in bipolar semiconductors are interdependent and self-consistent. In a general case, the distribution of the temperature in homogeneous semiconductors cannot be con-stant or a linear function with respect to the coordinate even in a linear approximation. The roles of nonequilibrium charge carriers and the recombination in the heat transport are established.
Key words: thermal nonequilibrium, recombination, quasineutrality, transport phenomena.
