    摘要: Artificial dielectrics using nanostructures, such as nanowires, are disclosed. In embodiments, artificial dielectrics using other nanostructures, such as nanorods, nanotubes or nanoribbons and the like are disclosed. The artificial dielectric includes a dielectric material with a plurality of nanowires (or other nanostructures) embedded within the dielectric material. Very high dielectric constants can be achieved with an artificial dielectric using nanostructures. The dielectric constant can be adjusted by varying the length, diameter, carrier density, shape, aspect ratio, orientation and density of the nanostructures. Additionally, a controllable artificial dielectric using nanostructures, such as nanowires, is disclosed in which the dielectric constant can be dynamically adjusted by applying an electric field to the controllable artificial dielectric. A wide range of electronic devices can use artificial dielectrics with nanostructures to improve performance. Example devices include, capacitors, thin film transistors, other types of thin film electronic devices, microstrip devices, surface acoustic wave (SAW) filters, other types of filters, and radar attenuating materials

    摘要: Multilayered microfluidic devices include structures that are used to align elements that make up the devices. Such elements include additional substrate layers, external sampling elements, and the like. In one embodiment, a multilayered microfluidic device includes first and second substrate layers attached one to the other, each substrate layer having a notch in an edge of the substrate layer. The notches are positioned such that they circumscribe a single opening into which an alignment key is inserted. In a method of fabricating a multilayered microfluidic device, notches are provided in first and second substrate layers, the notches circumscribing a single opening when the substrate layers are mated together. An alignment key is inserted into the single opening, and the substrate layers are bonded together. The alignment key may be, for example, a shim or a capillary element.
