Abstract

This work studies the influence of experimental conditions on the occurrence and development of oscillations of the open‐circuit potential (OCP) of silicon immersed in aqueous solution of 0.01 M CuSO~4~ + 0.06 M HF. The oscillations are very regular and last for days without any tendency to diminish. We show that they are quite sensitive to the temperature of the electrolyte, its viscosity, stirring, relative concentration of components, etc. We also present a phenomenological model to explain the oscillatory OCP behavior.
