Interaction of the thermal and concentration nonequilibriums in a bipolar semiconductor: Linear transport phenomena

It is shown that the transport of heat and electricity in bipolar semiconductors are interdependent and self-consistent. The correlation between the energy and concentration nonequilibrium is established: the recombination is proportional to the second derivative of the temperature with respect to the coordinate. In a general case, the distribution of the temperature in homogeneous semiconductors cannot be constant or a linear function with respect to the coordinate even in a linear approximation.
