In this work advances in the field of colloidal crystal assembly are discussed. The traditional route to colloidal crystal assembly has been gravitational sedimentation, but this process is slow, and gives rise to grain boundaries and defects in the bulk crystal. This work intends to remediate these problems by applying two techniques: electrophopretic deposition and templating. Electrophoretic deposition is a rapid technique with wide applicability and is well-suited to colloidal assembly on electrode surfaces. Templating can eliminate defects and give rise to colloidal crystals with predetermined morphologies. Polymer colloids (PMMA) were deposited on a number of patterned Indium Tin Oxide (ITO) electrode substrates and good ordering was observed. The commensurabilty between the colloids and the templates gave rise to confinement and matching effects. In order to better understand the process, real time in situ studies were conducted using optical microscopy. A model is proposed to explain the behaviour observed.
