Modulating two-dimensional non-close-packed colloidal crystal arrays by deformable soft lithography.
We report a simple method to fabricate two-dimensional (2D) periodic non-close-packed (ncp) arrays of colloidal microspheres with controllable lattice spacing, lattice structure, and pattern arrangement. This method combines soft lithography technique with controlled deformation of polydimethylsiloxane (PDMS) elastomer to convert 2D hexagonal close-packed (hcp) silica microsphere arrays into nc...
متن کاملTunable two-dimensional non-close-packed microwell arrays using colloidal crystals as templates.
In this paper we demonstrate a facile and efficient way to fabricate poly(dimethylsiloxane) (PDMS) molds with hexagonal non-close-packed (ncp) arrangements of microwells by casting PDMS prepolymer onto two-dimensional (2D) ncp colloidal crystals. The templates of the 2D ncp colloidal crystals were fabricated via coupling lift-up soft lithography and solvent-swelling. We found that the depths of...
متن کاملConformally Back-Filled, Non-close-packed Inverse-Opal Photonic Crystals
Photonic crystals (PCs) offer far greater control over the generation and propagation of light than any other material structures. Their defining characteristics, omnidirectional and directional photonic bandgaps (PBGs), can be manipulated to enable effects such as low losses in optical circuits and control of spontaneous emission. PCs are also creating much excitement because of their ability ...
متن کاملPhotonic band gaps in non-close-packed inverse opals
An advanced dielectric function has been designed to compute the photonic band structures of non-close-packed inverse opals fabricated using conformal infiltration and by a recently described sacrificial-layer technique. A model is proposed to correctly simulate complex dielectric structures resulting from conformal backfilled infiltrations. While large photonic band gaps PBGs and a reduced ref...
متن کاملNew Tetrahedrally Close-Packed Structures
We consider mathematical models of foams and froths, as collections of surfaces which minimize area under volume constraints. Combinatorially, because of Plateau’s rules, a foam is dual to some triangulation of space. We examine the class of foams known as tetrahedrally close-packed (TCP) structures, which includes the one used by Weaire and Phelan in their counterexample to the Kelvin conjectu...
