摘要:
An ionic device includes a layer (220) of an ionic conductor containing first and second species (222, 224) of impurities. The first species (222) of impurity in the layer (220) is mobile in the ionic conductor, and a concentration profile of the first species (222) determines a functional characteristic of the device (200). The second species (224) of impurity in the layer (220) interacts with the first species (222) within the layer (220) to create a structure (226) that limits mobility of the first species (222) in the layer (220).

Examples of integrated sensors are disclosed herein. An example of an integrated sensor includes a flexible substrate, and an array of spaced apart sensing members formed on a surface of the flexible substrate. Each of the spaced apart sensing members includes a plurality of polygon assemblies. The polygon assemblies are arranged in a controlled pattern on the surface of the flexible substrate such that each of the plurality of polygon assemblies is a predetermined distance from each other of the plurality of polygon assemblies, and each of the plurality of polygon assemblies including collapsible signal amplifying structures controllably positioned in a predetermined geometric shape.

Apparatus, methods, and hollow metal waveguides to perform surface-enhanced Raman spectroscopy are disclosed. An example apparatus includes a hollow metal waveguide to direct Raman photons from an intermediate location within a volume of the hollow metal waveguide toward a distal end of the hollow metal waveguide, and a mirror to direct incident light from a light source to the intermediate location within the volume of the hollow metal waveguide and to direct at least some of the Raman photons toward the distal end.

An apparatus for surface enhanced Raman spectroscopy includes a substrate, a nanostructure and a plasmonic material. The nanostructure and the plasmonic material are integrated together to provide electronic and plasmonic enhancement to a Raman signal produced by electromagnetic radiation scattering from an analyte.

Embodiments of the present invention are related to nanowire-based devices that can be configured and operated as modulators, chemical sensors, and light-detection devices. In one aspect, a nanowire-based device includes a reflective member, a resonant cavity surrounded by at least a portion of the reflective member, and at least one nanowire disposed within the resonant cavity. The nanowire includes at least one active segment selectively disposed along the length of the nanowire to substantially coincide with at least one antinode of light resonating within the cavity. The active segment can be configured to interact with the light resonating within the cavity.
