We report the properties of a field effect transistor (FET) and a gas sensor based on CuO nanowires. CuO nanowire FETs exhibit p-type behavior. Large-scale p-type CuO nanowire thin-film transistors (10(4) devices in a 25 mm(2) area) are fabricated and we effectively demonstrate their enhanced performance. Furthermore, CuO nanowire exhibits high and fast response to CO gas at 200 degrees C, whic...

We demonstrate a bottom-up/top-down combined method for the fabrication of horizontally suspended, well-oriented and size-controlled Si nanowire arrays. Mechanical beamlike structures composed of multiple ordered arrays consecutively linked by transversal microspacers are obtained by this method. Such structures are used to investigate the mechanical elasticity of the nanowire arrays by atomic ...

a r t i c l e i n f o Keywords: Pd nanowires Nonenzymatic and enzymatic bioelectrocatalysis Glucose oxidase Biofuel cells Bioelectrocatalysis was demonstrated with palladium (Pd) nanowire array electrode via nonenzymatic and en-zymatic methods for glucose, which was validated by the generation of anodic current in the presence of glucose. The vertically standing Pd nanowires used for the fabric...

silicon nanowire (sinw) arrays were produced by electroless method on polycrystalline si substrate, in hf/ agno3 solution. although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. in order to study the influence of etching time (which affects the sinws length) on d...

In this paper, the internal structure of novel multiphase gallium nitride nanowires in which multiple zinc-blende and wurtzite crystalline domains grow simultaneously along the entire length of the nanowire is investigated. Orientation relationships within the multiphase nanowires are identified using high-resolution transmission electron microscopy of nanowire cross-sections fabricated with a ...

The differential sensing of tyrosine and serine is achieved with well-aligned CdS nanowire arrays by exploring the pH-dependent photoluminescence behavior of the nanowire arrays toward exposure to the two amino acid solutions. The contrasting trend in photoluminescence (PL) intensity with respect to variations in analyte concentration observed at pH 11 served as the check point for the present ...

An effective procedure for the fabrication of patterned nanowire arrays with micron-sized features is presented. Photolithographic methods are utilized to form set patterns onto porous anodic alumina membranes (AAM), and these modified membranes can then be used in the electrochemical growth of nanowire arrays. This approach readily allows the formation of a variety of nanowire array patterns w...

Chemical vapor deposition (CVD) using gold nanoparticles as the catalyst to grow high-quality single-crystal gallium nitride nanowires was developed. This method enables control over several important aspects of the growth, including control of the nanowire diameter by using monodispersed gold clusters, control of the nanowire location via e-beam patterning of the catalyst sites, and control of...

y (1) Si nanowire models were constructed by density functional theory (DFT) using PBE atom potentials with spin polarization. Hydrogen atoms were used to terminate the surface silicon atoms of the nanowire. When the surface silicon atoms on nanowire were fully terminated by hydrogen atoms, the H/Si ratio was 0.92 (Fig.1 (a)) and when the surface silicon atoms were not maximally saturated, the ...
