Crystalline growth
WebJan 1, 2014 · The crystal growth proceeds as the stacks of lamellar crystals and amorphous layers in between. (c, e, f) When polymers are crystallized from the melt, concentrated solutions, or viscous liquids, a spherulitic structure is developed with radiating and space filling branches of the chain-folded lamellar crystallites. The spherulite is the … WebFlexible Photodetectors. In article number 2213888, Jinyou Xu, Ernesto Joselevic, and co-workers propose a universal strategy for the self-oriented growth of organic nanowires on faceted polymer films.Consequently, nanowires are integrated into photodetectors directly on a flexible film. This in-situ integration strategy helps nanowire-based flexible …
