Abstract:
The present invention relates to a method for creating nanostructures in and on organic or inorganic substrates comprising at least the following steps: a) providing a primary substrate having a predetermined refractive index; b) coating the primary substrate with one or more mediating layers each having a predetermined refractive index different from that of the primary substrate, wherein the sequence of the layers is arranged so that a predetermined gradient of the refractive index is generated between the primary substrate and the uppermost layer of the one or more mediating layers; c) optionally coating the uppermost layer of the one or more mediating layers with an additional top layer; d) depositing a nanostructured etching mask onto the uppermost layer of the composite substrate obtained after steps a)-b) or a) -c); e) generating protruding structures, in particular conical or pillar structures, or recessed structures, in particular holes, in at least the uppermost layer of the composite substrate by means of reactive ion etching. A further aspect of the invention relates to a composite substrate with a nanostructured surface obtainable by said method.
Abstract:
A method of ultra-high aspect ratio high resolution vertical directionality controlled metal- assisted chemical etching, V-MACE, is provided that includes forming a pattern on a substrate surface, using a lithographic or non-lithographic process, forming hole concentration balancing structures on the substrate, using a lithographic process or non- lithographic process, where the concentration balancing structures are proximal to the pattern, forming mechanical anchors internal or external to the patterned structures, forming pathways for etchant and byproducts to diffuse, and etching vertical features from the substrate surface into the substrate, using metal-assisted chemical etching, MACE, where the vertical features are confined to a vertical direction by the concentration balancing structures.
