Self-noise of molecular electronic transducers

Abstract

The effect of hydrodynamic fluctuations on noise in molecular electronic transducers is studied. It is shown that turbulent pulsation also makes a considerable contribution to the self-noise of molecular elec-tronic transformers, along with laminar flow fluctuations. A method for qualitative and quantitative calculation of the noise induced by turbulent pulsation that arises when a liquid flows along the electrode surface is proposed. A quantitative relationship that relates the rms pressure pulsation to the liquid head and an expression for the total spectral density of the hydrodynamic noise in molecular electronic transducers are obtained.
