Claims24
A substrate-supported array of spaced-apart nanowires comprising:
- a substrate;
- and
- disposed upon the substrate a plurality of spaced-apart, aligned and individually steerable nanowires having a ratio of a nanowire spacing to a nanowire height of at least 0.2 and a nanowire diameter in the a range of 1–500 nanometers, wherein the nanowire height is in a range of 0.1 to 200 micrometers, and a ratio of the nanowire height to the nanowire diameter is between approximately 4,500 and 10,000.
