Abstract: A method of positioning a catalyst nanoparticle that facilitates nanowire growth for nanowire-based device fabrication employs a structure having a vertical sidewall formed on a substrate. The methods include forming the structure, forming a targeted region in a surface of either the structure or the substrate, and forming a catalyst nanoparticle in the targeted region using one of a variety of techniques. The techniques control the position of the catalyst nanoparticle for subsequent nanowire growth. A resonant sensor system includes a nanowire-based resonant sensor and means for accessing the nanowire. The sensor includes an electrode and a nanowire resonator. The electrode is electrically isolated from the substrate. One or more of the substrate is electrically conductive, the nanowire resonator is electrically conductive, and the sensor further comprises another electrode. The nanowire resonator responds to an environmental change by displaying a change in oscillatory behavior.

Abstract: A semiconductor assembly is described in which a support element is constructed on a surface of a semiconductor lamina. Following formation of the thin lamina, which may have a thickness about 50 microns or less, the support element is formed, for example by plating, or by application of a precursor and curing in situ, resulting in a support element which may be, for example, metal, ceramic, polymer, etc. This is in contrast to a rigid or semi-rigid pre-formed support element which is affixed to the lamina following its formation, or to a donor wafer from which the lamina is subsequently cleaved. Fabricating the support element in situ may avoid the use of adhesives to attach the lamina to a permanent support element; such adhesives may be unable to tolerate processing temperatures and conditions required to complete the device. In some embodiments, this process flow allows the lamina to be annealed at high temperature, then to have an amorphous silicon layer formed on each face of the lamina following that anneal. A device may be formed which comprises the lamina, such as a photovoltaic cell.

Vibration of the nano-needle under the influence of the AC electric field facilitates detection of a Raman scattering signal from the analyte adsorbed on the nano-needle tip. The system further includes a synchronous detector configured to be gated cooperatively with the vibration of the nano-needle. The method includes inducing the vibration, illuminating the vibrating tip to produce a Raman signal, and detecting the Raman signal using the detector.

Abstract: Computer-implemented systems and methods are provided for reducing a number of options presented to a user where the options have characteristics that are arranged in a multi-dimensional hierarchical space. A system and method can be configured to identify common dimensions using dimension nodes in dimensional points and identify compatible nodes for each dimension in the multi-dimensional hierarchical space by determining whether an association exists. Compatible pairs of surviving points are generated after applying each of the compatible nodes from the common dimensions. Greatest lower bounds (GLBs) are computed for each of the generated compatible points, and a set of options is generated comprising points from the generated compatible points and the computed GLBs.

Abstract: An optical sensor, sensing system and method of sensing employ a half-core hollow optical waveguide adjacent to a surface of an optical waveguide layer of a substrate. The half-core hollow optical waveguide and the adjacent optical waveguide layer cooperatively provide both an optical path that confines and guides an optical signal and an internal hollow channel. The optical path and channel extend longitudinally along a hollow core of the half-core hollow optical waveguide. The system further includes an optical source at an input of the optical path and an optical detector at an output of the optical path. A spectroscopic interaction between an analyte material that is introduced into the channel and an optical signal propagating along the optical path determines a characteristic of the analyte material.
