[en] Current fluctuations conditioned by asymmetric fluctuations of the electron distribution function are studied. The fluctuations originate in equilibrium and homogeneous n-type semiconductors as a result of the random scattering between phonons. An expression for the current equilibrium fluctuation spectra S₁(ω) is obtained. It is shown that S₁∼ const in the range ω<ω₀. In the range ω₀<ω<ω₁ the frequency dependence of S₁ (ω) is described by the 1/ω law, and in the range ω>ω₁ by the 1/ω² law. The characteristic frequencies ω₁ and ω₀ are determined by the semiconductor parameters as well as by the electron and phonon diffusion and scattering processes in the momentum space
