Abstract: We present a confocal microscopy study of 1.55micrometers monodisperse silica hard spheres as they sediment and crystallize at the bottom wall of a container. If the particles sediment onto a featureless flat wall, the two bottom layers crystallize simultaneously and layerwise growth follows. If the wall is replaced by a hexagonal template, only layerwise growth occurs. Our results complement earlier numerical simulations and experiments on other colloidal systems.
