Before revision: For perceptible growth rates, this mechanism requires a finite driving force (or degree of supercooling) in order to lower the nucleation barrier sufficiently for nucleation to occur by means of thermal fluctuations.Volmer, M., "Kinetic der Phasenbildung", T. Steinkopf, Dresden (1939) In the theory of crystal growth from the melt, Burton and Cabrera have distinguished between two major mechanisms:E.M. Aryslanova, A.V.Alfimov, S.A. Chivilikhin, "Model of porous aluminum oxide growth in the initial stage of anodization", Nanosystems: physics, chemistry, mathematics, October 2013, Volume 4, Issue 5, pp 585 Non-uniform lateral growth The surface advances by the lateral motion of steps which are one interplanar spacing in height (or some integral multiple thereof).
