Patent ID: 8906733

Claim:
A method for creating a nanostructure, comprising: depositing a first material to at least partially fill spaces in a template of a second material thereby forming an array of nanocables comprising the first material, wherein the first material is a conductive metallic material; removing at least a portion of the second material such that any remaining portion of the second material forms an insulating layer between each nanocable within the array of nanocables; and forming at least one layer over the nanocables, wherein the at least one layer forms a respective photovoltaically active p-n junction over each one of the nanocables in the array of nanocables, wherein the nanocables are arranged in a brush configuration wherein each one of the nanocables in the array of nanocables extends along a first direction and is spaced apart from the other ones of the nanocables in the array of nanocables in a second direction transverse to the first direction.
