Continuous Convective Assembling of Fine Particles into Two-Dimensional Arrays on Solid Surfaces

摘要: Forming regular textures of an arbitrary size on smooth solid surfaces is the challenge future technology to produce new types optical gratings, filters, antireflective surface coatings, selective solar absorbers, data storage, and microelectronics. Here we present a novel approach form such sophisticated textures:  controlling growth particle arrays wettable surfaces. The obtained centimeter-size polycrystalline monolayer films consist closely packed fine particles. Coloring which arises from light diffraction, interference, scattering exclusively inherent in textured shows differently oriented crystal domains building film. results show that higher monodispersity, lower volume fraction, environmental humidity, larger forming domains.
