A Unified Theory of 1/f Noise and Dielectric Response in Condensed Matter.

Abstract:

A theoretical model of mobility fluctuations that has a 1f power spectra in electric current conducting materials and devices is presented. The theory traces the origin of the 1f noise to some rather uncommon electronic or ionic energy structure and excitations which have been identified earlier to be responsible for the remarkable universal dielectric response behavior of condensed matter. The relation between the ubiquitous 1f noise and the universal 1omega to the 1-n power low frequency dielectric response in current conducting material is pointed out and emphasized. We have thus a unified theory explaining on the same basis both physical phenomena with a single physical picture. Author
