Abstract: We investigate the nature of the ordered phase for a model of colloidal particles confined within a quasione-dimensional Q1D strip between two parallel boundaries, or walls, separated a distance D in two dimensions 2D . Using Monte Carlo simulations we find that at densities typical of the bulk 2D triangular solid the order in the D1D strip is determined by the nature of the boundaries. While the order is enhanced for a suitably corrugated boundary potential, for a uniformly repulsive smooth boundary potential ordering normal to the walls is enhanced “layering” , but destroyed parallel to the wall.
