Abstract
Uniformly sized microspheres confined to thin layers between solid boundaries are used to demonstrate pattern formation in diffusion-controlled aggregation. Extremely slow growth processes monitored over several months show faceted hexagonal lattices. For successively faster growth, dendritic crystals and ramified aggregates are formed. The results are compared with recent studies of local and global growth models.Keywords
