Abstract: There is provided a substrate comprising an array of non-pillar-shaped nanoformations extending from the surface of the substrate and being arranged to form, between adjacent non-pillar-shaped nanoformations, longitudinally shaped nano-sized depression formations, said nanoformations and said depressions being selected to enable the surface of the substrate to exhibit a higher pinning force relative to the surface of a substrate with an array of pillar-shaped formations.

Abstract: An antiretlective biomimetic hierarchical structure, a composite antiretlective hierarchical structure, and an antiretlective surface including a pattern of antiretlective biomimetic hierarchical structures are provided. The antiretlective hierarchical structures include one or more clusters of primary structures and a plurality of secondary structures formed on each of the primary structures. The primary structures have dimensions in the micrometer range with a major dimension of approximately two micrometers. Each of the secondary structures has dimensions in the nanometer range wherein the pitch and height are approximately three hundred nanometers.
