We report colloid crystal growth by using electrodeposition of charged polymer colloid particles on patterned conductive substrates. We used photolithography to create patterns with conductive grooves and dielectric ribs on indium-tin oxide surfaces. Two approaches were used to enhance long-range order in two-dimensional colloid crystals grown on patterned surfaces: (i) patterning of substrates with features commensurate with several particle diameters and (ii) patterning of substrates with features commensurate with a single particle diameter. We demonstrate the effect of commensurability on colloid crystal growth and present the results of real-time studies of colloid crystallization in constrained geometry during electrodeposition on patterned substrates.
