Paper Abstract

We developed a visualization method to display nano-particles and their dynamic 2D growth and coalescence on surfaces, due to mechanisms such as adsorption, diffusion and coalescence. The method relies on 2D spatial Fourier frequency transforms (FT) of 2D image density functions representing the details of the x-y-z nanostructure. These images are convoluted using FT of spatio-temporal integrodifferential equations involving models of the physical driving forces in the spatial frequency domain. Surface growth and restructuring effects taking place during photo-deposition processes were investigated. In particular, the dynamic changes of photo-deposited nanoparticles morphology during sub-monolayer growth were simulated. The comparison of simulation and sampled Scanning Electron Microscopy (SEM) micrographs of photo deposited thin films during monolayer formation were in good agreement.
