The growth process is governed by the convection and diffusion field. The convective diffusion field is simulated by the biased-random walker resulting from a superimposed drift that represents the convective flow. The development of distinct morphologies is found with varying direction and strength of drift. By introducing a horizontal drift parallel to the deposition plate, the diffusion-limited deposit changes into a single needle inclined to the plate. The width of the needle decreases with increasing strength of drift. The angle between the needle and the plate is about 45° at high flow rate. In the presence of an inclined drift to the plate, the convection-diffusion-limited deposit leads to the formation of a characteristic columnar morphology. In the limiting case where the convection dominates, the deposition process is equivalent to ballistic deposition onto an inclined surface.7 p.application/pdfeng(c) The American Physical Society, 1991ElectroquímicaFísica estadísticaProcessos estocàsticsElectrochemistryStatistical physicsStochastic processesMorphological changes in convection-diffusion-limited depositioninfo:eu-repo/semantics/article72007info:eu-repo/semantics/openAccess
