Influence of adsorption and diffusion rates on the growth of Pb1-x Fex S nanoparticle films.
We study the effect of adsorption rate on the particle size distribution in solution-grown ternary Pb1-x Fex S nanoparticle films. Computer simulations of a stochastic lattice model with adsorption and mass dependent diffusion have been performed to mimic the underlying mechanism of particle growth. The experimental as well as numerical data exhibit identical scaling with respect to the incident flux rate. A transmission electron microscope analysis of Pb1-x Fex S nanoparticle films reveals self-similarity in the particle size distributions corresponding to different adsorption rates as a manifestation of the observed scaling.
