Abstract
An apparatus has multiple sets of independently addressable interdigitated nanowires. Nanowires of a set are in electrical communication with other nanowires of the same set and are electrically isolated from nanowires of other sets.
Claims20
An apparatus comprising:
- a first set of nanowires;
- and
- a second set of nanowires interdigitated with the first set of nanowires, wherein the first set of nanowires and the second set of nanowires are formed of electrically conductive material, and wherein the first set of nanowires is independently electrically addressable and electrically isolated from the second set of nanowires.
A method comprising:
- forming a first set of nanowires on an electrically conductive substrate;
- providing an insulator layer on the electrically conductive substrate between the nanowires of the first set of nanowires, wherein the insulator layer partially coats the nanowires of the first set of nanowires;
- forming a second set of nanowires on the insulator layer, wherein the nanowires of the second set of nanowires are interdigitated with the nanowires of the first set of nanowires, wherein the first set of nanowires and the second set of nanowires are formed of electrically conductive material;
- and
- providing an electrically conductive layer on the insulator layer, wherein the electrically conductive layer electrically connects the nanowires of the second set of nanowires with each other.
