    摘要： A nanowire-based photonic device and an array employ nanowires connecting between coaxially arranged electrodes in a non-uniform manner along a vertical extent of the electrodes. The device includes a pair of the electrodes separated by a circumferential gap. The nanowires chaotically emanate from an inner electrode of the pair and connect across the circumferential gap to an outer electrode of the pair. The array includes an outer electrode having an interconnected pattern of cells and inner electrodes, one per cell, arranged coaxially with and separated from the outer electrode by respective circumferential gaps. The nanowires chaotically emanate from the inner electrodes and connect across the respective circumferential gaps of the cells to the outer electrode. The device and the arrays further include a semiconductor junction between the electrodes.

    摘要： Embodiments of the present invention are directed to nanowire-based systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system comprises a substrate (102) having a surface and a plurality of tapered nanowires (104) disposed on the surface. Each nanowire has a tapered end directed away from the surface. The system also includes a plurality of nanoparticles (110) disposed near the tapered end of each nanowire. When each nanowire is illuminated with light of a pump wavelength, Raman excitation light is emitted from the tapered end of the nanowire to interact with the nanoparticles and produce enhanced Raman scattered light from molecules located in close proximity to the nanoparticles.

    摘要： A method of forming nanostructures using catalyst-free epitaxial growth includes depositing a first layer of a non-single crystalline material on a support structure; heating the support structure and the first layer such that a combined layer is formed; and growing a nanostructure on the combined layer. A hetero-crystalline includes a support structure; a first layer of non-single crystalline material deposited on the support structure and combined with the support structure or a second layer to form a combined layer; and a nanostructure of a single crystalline material grown on the combined layer.
