Methods and Structures for Self-assembly of Anisotropic 1D Nanocrystals

摘要: In the nanoscience and nanotechnology, study of nanocrystal self-assembly has been regarded as a key technology in leading future industrial development. The colloidal techniques, particularly for one-dimensional (1D) building blocks, have widely adopted systematic fabrication functional nanocrystals received an extensive research attention. However, increase blocks’ anisotropy, e.g. from sphere to rod/wire, dramatically leveled up difficulty organizing them into ordered structures. To realize tailored 1D self-assembled structures, profound understanding detailed design mechanism procedures are much needed. Here, thorough review over methods alignments present achieve large-scale Through different such evaporation, template, electric field, Langmuir-Blodgett film chemical bonding, with various shapes can be on substrates, at interfaces solutions. These assembled structures that achieved so far, exhibit degrees alignments, stripe pattern non-close-packed structure, horizontal, vertical close-packed monolayers, nematic, semectic AB stacking three-dimensional (3D) assembly multilayers. general, these techniques reach small dimension create microstructures possess unique properties their individual blocks.
