    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： This disclosure provides systems, methods and apparatus for fabricating thin film transistor devices. In one aspect, a substrate having a source region, a drain region, and a channel region between the source region and the drain region is provided. The substrate also includes an oxide semiconductor layer, a first dielectric layer overlying the channel region, and a first metal layer on the dielectric layer. A second metal layer is formed on the oxide semiconductor layer overlying the source region and the drain region. The oxide semiconductor layer and the second metal layer are treated to form a heavily doped n-type oxide semiconductor in the oxide semiconductor layer overlying the source region and the drain region. An oxide in the second metal layer also can be formed.

    摘要： 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.
