• The thermodynamical theory is extended to the hot electron problem and irreversible entropy production is calculated. On the minimum principle of entropy production it is derived that the electron temperature is not uniform in bulk semiconductors, even of the lattice temperature is kept constant. Instability conditions for the electron density wave is discussed. In the case that the dielectric relaxation frequency is larger than the frequency of the density wave, the instability occurs when the differential conductivity is negative. When the relaxation frequency is smaller than the frequency of the density wave, the instability condition is found to depend on the detailed properties of the system and is not directly related to the static behavior of the conductivity.
