  • Patent number: 9986941
    Abstract: Improved monitoring of one or more blood coagulation factors is provided. Factor-specific molecular probes having a dye-quencher arrangement are employed. In preferred embodiments, a compact integrated optical source and detector device is used for fluorescence measurements. Continuous and real-time monitoring of the activity of one or multiple blood factors is provided.

  • Publication number: 20170010258
    Abstract: The invention relates to a novel biosensor, the metal-insulator transition (MIT) point biosensor, a non-expensive miniaturized device, having a small footprint and high sensitivity, which can measure molecular interactions or the presence of small amounts of molecules without the need for the molecules to be labeled. The sensor comprises a vanadium dioxide (V02) layer located between two metal measuring pads. The introduction of molecules of interest to the sensor surface results in changes in the oxide interface charge density that can be detected by a shift in the metal oxide transition point and differences in the amount of current passing through the oxide. The MIT biosensor is useful for the detection of charged molecules, including macromolecules, such as proteins or nucleic acids as well as other types of particles, such as cells, bacteria, or viruses.

  • Publication number: 20160293787
    Abstract: A solar cell has a nanostructured window layer with planar p-n junction geometry. Preferably, metal grid mesas are used to provide lateral conductance and good electrical contacts. In addition to carrier confinement and lateral conductance, this window layer can also provides a broadband angle-independent antireflection function. This structure enhances both the optical and electrical properties in a solar cell, leading to higher Jsc, Voc, FF (fill factor) and efficiency. The absorption in the window layer is partially converted to photocurrent, which to some extent compensates for the self-absorption loss due to its greater thickness. This design can eliminate the need for a separate anti-reflection coating.

  • Patent number: 9379261
    Abstract: Improved solar cells are provided by nano-structuring the solar cell active region to provide high optical absorption in a thin structure, thereby simultaneously providing high optical absorption and high carrier collection efficiency. Double-sided nano-structuring is considered, where both surfaces of the active region are nano-structured. In cases where the active region is disposed on a substrate, nano-voids are present between the substrate and the active region, as opposed to the active region being conformally disposed on the substrate. The presence of such nano-voids advantageously increases both optical and electrical confinement in the active region.

  • Publication number: 20150047702
    Abstract: Photovoltaic devices conformally deposited on a nano-structured substrate having hills and valleys have corresponding hills and valleys in the device layers. We have found that disposing an insulator in the valleys of the device layers such that the top electrode of the device is insulated from the device layer valleys provides beneficial results. In particular, this insulator prevents electrical shorts that otherwise tend to occur in such devices.

  • Patent number: 8306607
    Abstract: Characteristics of biological substances, such as cerebral cortex matter, are sensed. According to an example embodiment, the present invention is directed to a negligibly-intrusive, multi-layer integrated circuit arrangement for monitoring activity of an area of a cerebral cortex that would normally be covered by an anatomical layer. The multi-layer integrated circuit arrangement includes an optics layer located outside the cerebral cortex area that includes an emitter and a detector. The optics layer is adapted for implantation in the anatomical layer and for sensing at least one brain-activity parameter. The multi-layered integrated circuit arrangement also includes a data-processing layer that includes a digital-processing circuit that is adapted for assimilating neural data in response to the optics layer sensing at least one brain-activity parameter.

  • Publication number: 20120006390
    Abstract: Solar cells or photodetectors having one or more single-crystal shell layers conformally deposited on Ge nano-wires are provided. This approach can provide higher efficiency and/or reduced material cost compared to conventional planar approaches for multi-junction solar cells having the same thickness of active solar absorption materials. Shell layers deposited on the Ge nano-wires and including pn junctions can be grown such that they end up with single-crystal faceted tips, which can significantly improve optical collection efficiency and can improve the electron collection efficiency because of the high crystal quality.

  • Patent number: 7902046
    Abstract: Growth of SiGe on a significantly lattice mismatched substrate (e.g., Si) is provided by depositing a SiGe buffer layer at a growth temperature, then annealing the resulting structure at a temperature higher than the growth temperature. Additional buffer layers can be included following the same steps. The SiGe buffer is significantly lattice mismatched with respect to the substrate, and is preferably substantially lattice matched with a SiGe device to be grown on top of the buffer. The resulting buffer structure is relatively thin and provides low defect density, and low surface roughness. Disadvantages of thick graded buffer layers, such as high cost, high surface roughness, mechanical fragility, and CTE mismatch, are thereby avoided.

  • Patent number: 7645626
    Abstract: In connection with an optical-electronic semiconductor device, improved photoluminescent output is provided at wavelengths approaching and beyond 1.3 ?m. According to one aspect, a multiple quantum well strain compensated structure is formed using a GaInNAs-based quantum well laser diode with GaNAs-based barrier layers. By growing tensile-strained GaNAs barrier layers, a larger active region with multiple quantum wells can be formed increasing the optical gain of the device. In example implementations, both edge emitting laser devices and vertical cavity surface emitting laser (VCSEL) devices can be grown with at least several quantum wells, for example, nine quantum wells, and with room temperature emission approaching and beyond 1.3 ?m.
