Abstract
Systems and methods for providing a hybrid integrated nanostructure and nanotube substrate system are disclosed. The system includes a substrate having a plurality of nanostructures formed thereon. Interconnected to the substrate, directly or through nanostructures, are nanotubes. The nanostructures can extend for a greater distance from the surface of the substrate than the nanotubes, providing a robust structure. In addition, the structure can be highly emissive and absorptive hybrid surface.
