چکیده انگلیسی
Processes of origin and relaxation of fluctuations of the conduction electrons' distribution function in space-homogenous and non-degenerate thermal equilibrium semiconductors are discussed. It is shown that in low-frequency region the Fourier-component of the long-wavelength electrons and phonons distribution function's fluctuating component is directly proportional to Ï-1/2. It is shown that electron energy and/or quasi-momentum fluctuations may contain the Schönfeld pulse and that the Schönfeld model can directly be incorporated into physical model describing 1/f-type noise formation in semiconductors. It is suggested that the concept of “Thermal Equilibrium Semiconductor” can be reconsidered when one studies fluctuation phenomena, in particular 1/f-noise. It is demonstrated that the electron-phonon system always stays in non-equilibrium condition from point of view of the fluctuation theory.
