Nonlinear evolution of surface morphology under shadowing.
نویسندگان
چکیده
Fluorocarbon thin-film deposition is studied, which shows an anomalous high dynamic growth exponent and therefore does not fit in any universal class of fractal surface growth models. A detailed analysis of the nonlinear behavior of the surface morphology evolution is carried out, quantifying several features of the shadowing instability. A synergy effect with the Kardar-Parisi-Zhang nonlinearity, which couple the large scales induced by shadowing with intermediate scales, may explain the anomalous high growth exponent.

In the wave scattering from rough surfaces investigated by using the surface morphology and the vertical AFM, in general the correct and complete results cannot be obtained. If the roughness with respect to the wavelength is more than a critical limit, the theoretical calculation is not the same as the experimental data, and this inequality cannot be corrected without considering the shadowing...

In this simulation model, oblique angle deposition method and Monte Carlo random walks have been used. Growth model was ballistic deposition (BD). Incident particles flux comes to substrate at an angle with respect to normal. Two physical factors including self-shadowing and mobility limitation of incident particles make structures similar to independent columns with different shapes and separa...
متن کاملMound formation in surface growth under shadowing
In this paper we report on the morphological evolution of thin films grown by commonly employed deposition techniques, such as sputtering and chemical vapor deposition. In these deposition techniques, an angular distribution of incident particle flux leads to the shadowing effect, which often plays an important role in defining the growth front morphology. We show both by simulations and experi...
متن کاملHydrodynamic shadowing effect during precipitation of dendrites in channel flow.
A supersaturated fluid flowing over a reactive, rough surface leads to complex precipitation patterns. We study the growth and interaction between discrete precipitates along a reactive wall in a nonlaminar channel flow. We show that the competition between advective transport, diffusion, and mixing strongly influences the downstream precipitates morphology and the typical correlation length be...
