Abstract

The properties of two-dimensional (2D) colloidal crystals have been widely investigated during the last 20 years, but only little attention has been paid to effects of finite system size. We use video-microscopy to study small 2D crystals consisting of approximately 10 to 100 particles confined in hexagonal, circular and square regions. The observed crystal structures are strongly dominated by the shape of those regions and anisotropic diffusion coefficients, indicating a reduced mobility perpendicular to the walls.
