摘要：

We first grow two-dimensional crystals of nanometer latex particles from a thin film of water suspension placed on a flat solid substrate. The crystallization is performed by controlling the evaporation rate of water and the meniscus profile. The kinetic observations of the crystallization demonstrate two distinct processes: nucleation, preceded by thinning of the thin liquid film, and crystal growth. The crystal grows linearly in size, and its area increases as a quadratic function of time, due to the convective influx of particles from the suspension. A simple model of crystal growth interprets the kinetic data.
