Abstract

A theory for conductivity fluctuations in water-in-oil microemulsions is presented. The treatment is based on the charge fluctuations model proposed by Eicke et al., Hall, and Halle. The portion of current fluctuations due to fluctuations in the number of charge carriers is attributed to the charge generation-recombination equilibrium: two neutral drops ⇌ positive drop+negative drop. The power spectrum of the fluctuations is a Lorentzian determined by the forward and reverse rates of this equilibrium. Implications of the charge fluctuation model for experimental studies of water-in-oil microemulsions are suggested.
