Abstract
Official abstract text for this publication.
The invention relates to a method for making a 3D nanostructure having a nanosubstructure, comprising the steps of: i) providing a mold comprising at least one sharp concave corner; ii) conformational depositing at least one structural material in the sharp concave corner; iii) isotropically removing structural material; iv) depositing at least one other structural material; v) removing earlier deposited structural material; vi) forming a nanosubstructure; and vii) removing the mold thereby providing the 3D nanostructure having the nanosubstructure.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for making a 3D nanostructure having a nanosubstructure in the form of a 3D oriented horizontal or horizontal and vertical nanowire, comprising the steps of: i) providing a mold comprising at least one horizontal or one horizontal and vertical sharp concave corner; ii) conformal depositing at least one structural material in at least the sharp concave corner; iii) isotropically removing a portion of structural material deposited in step ii…
