Template-Induced Growth of Close-Packed and Non-Close-Packed Colloidal Crystals during Solvent Evaporation

Abstract: Template-induced colloidal deposition during solvent evaporation is a promising technique for extending the possibilities of nanosphere lithography and the creation of photonic band gap materials. We investigated the influence of the parameters that determine the surface topography of templates on colloidal crystal structure. On pillar-shaped templates, large defect-free square symmetric monolayers, ordered vacancy arrays, and body-centered cubic (bcc) and simple cubic (sc) colloidal crystals could be grown. C… Show more

“…This makes self-assembly very promising because it could be used in patterned storage media to increase the storage densities currently available on hard disks up to an estimated density of 1 Tbit/in 2 [2]. Advances in the use of various methods for self-assembly have been made [3][4][5][6][7][8][9]. However, orientation and long-range ordering of the selfassembled template remains a problem.…”

“…Guided block copolymer self-assembly has been studied showing remarkable guiding effects, 7 and lithographically defined patterns have been used to aid close packed sphere self-assembly. [8][9][10][11][12][13] In comparison with block copolymers, close packed sphere self-assembly techniques are significantly different as they can produce arrays of three-dimensional ͑3D͒ magnetic spherical structures in dimensions not accessible by any other means. Block copolymer techniques do not allow control of the shape of the nanostructures.…”

“…[7,8] Colloidal particle crystals and patterned colloidal particles are most often formed using processes such as gravity sedimentation, [9] spin-coating, [10][11][12] electrostatic self-assembly, [2,13] convective deposition, [14,15] and self-assembly under physical confinement. [16,17] Most reports have focused on template-directed colloidal self-assembly where the template is defined before the nanoparticles are deposited.…”
