摘要： The present invention relates to a system and process for producing a nanowire-material composite. A substrate having nanowires attached to a portion of at least one surface is provided. A material is deposited over the portion to form the nanowire-material composite. The process further optionally includes separating the nanowire-material composite from the substrate to form a freestanding nanowire-material composite. The freestanding nanowire material composite is optionally further processed into a electronic substrate. A variety of electronic substrates can be produced using the methods described herein. For example, a multi-color light-emitting diode can be produced from multiple, stacked layers of nanowire-material composites, each composite layer emitting light at a different wavelength.

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： A nanowire varactor diode and methods of making the same are disclosed. The structure comprises a coaxial capacitor running the length of the semiconductor nanowire. In one embodiment, a semiconductor nanowire of a first conductivity type is deposited on a substrate. An insulator is formed on at least a portion of the nanowire's surface. A region of the nanowire is doped with a second conductivity type material. A first electrical contact is formed on at least part of the insulator and the doped region. A second electrical contact is formed on a non-doped potion of the nanowire. During operation, the conductivity type at the surface of the nanowire inverts and a depletion region is formed upon application of a voltage to the first and second electrical contacts. The varactor diode thereby exhibits variable capacitance as a function of the applied voltage.

摘要： A common deflection signal is provided, simultaneously, to individual yokes in an electron beam (e-beam) deflection apparatus of an electron beam projection lithography system. A single digital-to-analog converter (DAC) generates the common deflection signal. The common deflection signal is provided to individual programmable attenuators to adjust the signal for each individual yoke. The adjusted individual signal is amplified and passed to one of the individual yokes. The yokes are controlled to provide a curvilinear variable axis lens (CVAL) deflection that is adjusted to attenuate most of the noise from the common deflection signal that would have been present in a typical CVAL e-beam system.
