Abstract

Measurements of the frequency and temperature dependence of the noise spectrum and of its frequency exponent were performed on thick-film resistors and, together with the direct plots vs. the frequency logarithm of the spectrum-frequency product, they are used to check the island model of the flicker noise. The wide dispersion of the island relaxation times, necessary to originate the flicker noise, is due to tunnel emission and/or thermal activation processes of electrons from localized states, and to the exponential dependence of their emission probability on random variable distances and activation energies, whose distribution functions, means, and variances are determined both theoretically and experimentally.
