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.

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.

The present invention is directed to thin film transistors using nanowires (or other nanostructures such as nanoribbons, nanotubes and the like) incorporated in and/or disposed proximal to conductive polymer layer(s), and production scalable methods to produce such transistors. In particular, a composite material comprising a conductive polymeric material such as polyaniline (PANI) or polypyrrole (PPY) and one or more nanowires incorporated therein is disclosed. Several nanowire-TFT fabrication methods are also provided which in one exemplary embodiment includes providing a device substrate; depositing a first conductive polymer material layer on the device substrate; defining one or more gate contact regions in the conductive polymer layer; depositing a plurality of nanowires over the conductive polymer layer at a sufficient density of nanowires to achieve an operational current level; depositing a second conductive polymer material layer on the plurality of nanowires; and forming source and drain contact regions in the second conductive polymer material layer to thereby provide electrical connectivity to the plurality of nanowires, whereby the nanowires form a channel having a length between respective ones of the source and drain regions.

Embodiments of the present invention are provided for improved contact doping and annealing systems and processes. In embodiments, a plasma ion immersion implantation (PIII) process is used for contact doping of nanowires and other nanoelement based thin film devices. According to further embodiments of the present invention, pulsed laser annealing using laser energy at relatively low laser fluences below about 100 mJ/cm2 (e.g., less than about 50 mJ/cm2, e.g., between about 2 and 18 mJ/cm2) is used to anneal nanowire and other nanoelement-based devices on substrates, such as low temperature flexible substrates, e.g., plastic substrates.
