The low-frequency broadband noise of K0.3MoO3 associated with the sliding motion of charge-density waves (CDW) was measured in the frequency range between 1 mHz and 1 MHz. The power spectrum of voltage fluctuation consists of several peaks and the 1⁄fα background spectrum. As a result of an analysis, the former was found to be directly related to the energy distribution of the hopping among metastable states of the CDW’s, and the energy distribution was estimated from the experimental data. On the other hand, the latter is considered to come from the interaction among semi-macroscopic moving CDW domains, which are weakly coupled with each other.
