Abstract
The results of detailed experimental and theoretical investigation of 1/f noise in hopping conductivity are reviewed. The noise is related to fluctuations of the hopping site energies originated due to `external' (with respect to the percolation clusters) fluctuators of electronic or structural nature. The problem of the lowest cut-off frequency is discussed. The theoretical results are in satisfactory agreement with the experimental data obtained for the nearest neighbor hopping regime. An increase of the noise with temperature decrease in the variable range hopping regime is predicted.
