Surface self-assembly of colloidal crystals for micro- and nano-patterning

Colloidal Crystals-Self-Assembly of Monodispersed Colloidal Particles-

Colloidal crystals are three-dimensionally periodic lattices assembled from monodispersed spherical colloids. The ability to crystallize spherical colloids into spatially periodic structures has enabled interesting and often useful functionality not only from the constituent colloidal particles, but also from the long-range order exhibited by these periodic structures. A variety of methods by w...

Self-assembly and tunable mechanics of reconfigurable colloidal crystals

We investigate the self-assembly of crystals from reconfigurable colloidal building blocks. The building blocks possess the unique ability, inspired by recent experiments, to continuously alter their shape before, during, and after assembly. Using molecular simulations, we report the assembly of a reconfigurable degenerate crystal containing a fractionally filled kagome sublattice. We show that...

Assembly of Colloidal Crystals at Electrode Interfaces

We describe a theory for a new type of colloid behavior whereby particles deposited on a surface by electrophoresis aremanipulated to form two-dimensional crystals. Since the particles are equally charged, the clustering is opposite that expected from electrostatic considerations. Such behavior is consistentwith migrationdue to electrohydrodynamic flowsassociatedwithpolarization layers and ion ...
