Wh. Mulder, A MATHEMATICAL-DESCRIPTION OF THE CURRENT FLOW DURING PHASE-TRANSITIONS IN SOLID-SURFACE FILMS, Journal of electroanalytical chemistry [1992], 366(1-2), 1994, pp. 287-293
A mathematical treatment is presented with the aim of describing the t
ime course of the coverage of an electrode surface by a metallic depos
it layer or a solid-like organic monolayer when the film undergoes a p
hase transition, i.e. when the metal layer dissolves or a solid-liquid
/gas transition in organic films takes place. An approximate expressio
n is derived for the current which flows through the cell as a respons
e to this process, assuming that the dissolution of the solid phase is
initiated at patch boundaries and proceeds as a progressive shrinkage
of these patches.
