One-dimensional Phase-Change Nanowires for Information Storage Application

Sun X.H., Yu B., NASA Ames Research Center, US

The electrically operated phase-change random access memory (PRAM) features faster write/read, improved endurance, and much simpler fabrication as compared with the traditional transistor-based nonvolatile semiconductor memories. Low-dimensional phase-change materials in nanoscale dimensions offer advantages over [...]

Growth of Ge nanowires by chemical vapour deposition technique

Phani A.R., Grossi V., Passacantando M., Ottaviano L., Santucci S., National Institute of Nuclear Physic, IT

Germanium, Mn doped Ge nanowires have been synthesized using chemical vapor deposition with Au nanoparticles (with size ranging from 5nm to 10 nm) as nucleating centers (catalysts) and Germanium, Manganese powders as a source for [...]

Mobility of Electrons in Rectangular Si Nanowires

Ramayya E., Vasileska D., Goodnick S.M., Knezevic I., Arizona State University, US

We investigate two issues in this paper. First, we examine the role of interface-traps on the device drain current in an SOI nanowire MOSFET. Afterwords, we investigate the role of the interface-roughness on the low-field [...]

Production of Conducting Polymer Nanowires for Use as Intravascular Neural Recording Electrodes

Ruddy B., Watanabe H., Hunter I., Llinás R.R., Massachusetts Institute of Technology, US

A crucial factor limiting the adoption of brain-machine interfaces is the invasiveness of conventional microelectrode arrays. Recently, Llinas et al. proposed a new, less invasive form of microelectrode array, utilizing sub-micrometer insulated platinum wires placed [...]

Mechanical Properties Measurement of Nanowires Anisotropic Conductive Film by Nanoindentation Technique

Hsu Y-Y, Lin R.J., Kuo T-Y, Su Y-Y, Uang R-H, Cheng H-C, Industrial Technology Research Institute, TW

In this investigation, a new type of anisotropic conductive film composed by nanowires and polymer was developed. Anodic aluminum oxide (AAO) film was uses as a template to obtain cobalt nanowires by electro-deposition. Low viscous [...]

Characterization of Aluminum Nitride Nanostructures by XANES and FTIR Spectroscopies with Synchrotron Radiation

Bellucci S., Balasubramanian C., Cinque G., Marcelli A., Cestelli Guidi M., Piccinini M., Popov A., Soldatov A., Onorato P., INFN-Laboratori Nazionali di Frascati, IT

We investigated nano-systems of AlN synthesized by DC arc-plasma-induced melting of aluminum in a nitrogen–argon ambient. Actually, the reaction of molten Al with N2 gas yields on a water-cooled surface a mixture of both nanowires [...]

Cell Separation and Manipulation by magnetic field in the presence of functionalised magnetic nanowires

Prina-Mello A., Diao Z., Coey J.M.D., CRANN Research Laboratory, IE

In this paper we investigate the possibility of using magnetic nanowires in cell separation and manipulation. Ni, Co/Cr and Co/Fe nanowires made by electrochemical deposition in anodic aluminum oxide (AAO) templates. The combination between nanowires [...]

Self-Assembled Cluster Nanostructures and Nanodevices

Brown S.A., Partridge J., Scott S., Reichel R., Ayesh A., Tee K.C., Nano Cluster Devices Ltd, NZ

In this paper we will review our efforts over the last few years to achieve contacted electronic devices which are self-assembled from atomic clusters. The focus is on the assembly of nanowires but many aspects [...]

Wafer Scale Aligned Sub-25nm Metal Nanowires on Silicon (110) using PEDAL Lift-off Process

Sonkusale S.R., Amsinck C.J., Nackashi D.P., Di Spigna N.H., Barlage D., Johnson M., Franzon P.D., North Carolina State University, US

We have demonstrated a new PEDAL process to make sub-25 nm nanowires across the whole wafer. The PEDAL process is useful in the fabrication of metal nanowires directly onto the wafer by doing shadow metalization [...]

Growth and Characterization of GaAs/AlGaAs Core-Shell Nanowires and AlGaAs Nanotubes

Noborisaka J., Motohisa J., Hara S., Fukui T., Hokkaido University, JP

We report on the fabrication of GaAs/AlGaAs core-shell nanowires (NWs) and AlGaAs nanotubes by SA-MOVPE and their photoluminescence characterization. The fabrication started from a preparation of patterned GaAs (111) B substrates partially covered with SiO2 [...]
