Abstract
Substrates having nanostructures disposed thereon and methods of forming nanostructures on the substrates are disclosed.
Claims43
A structure, comprising:
- a substrate having a non-planar surface, wherein a portion of the non-planar surface has at least one layer of nanostructures disposed thereon, wherein the substrate is a symmetrical structure having one center axis of rotation, and wherein the nanostructures have a length of about 10 nanometers (nm) to 5000 nm.
A method for forming nanostructures comprising:
- rotating a substrate having a non-planar surface at an angle θ, where θ is the angle defined by a vapor arrival line and a center axis of rotation of the substrate, wherein the substrate is a symmetrical structure having one center axis of rotation;
- rotating the non-planar substrate about its center axis of rotation;
- exposing the non-planar substrate to a vapor flux of a first type of material as the substrate rotates, wherein the exposure is at a temperature of less than a melting point of the material;
- and
- forming nanostructures on the substrate.
