Flexible Morphology Control of Nanotube Arrays from Glancing Angle Deposition

Huang Z.F., Harris K.D., Brett M.J., University of Alberta, CA

Recently, silicon nanotubes (SiNTs) have attracted considerable attention. However, it has been challenging to grow SiNTs without any template. Another challenge is to engineer the shape of SiNTs, which to date has been limited mostly [...]

Synthesis and Characterization of Anodized Titanium Oxide Nanotubes Arrays

Hu M.Z., Lai P., Bhuiyan M.S., Tsouris C., Gu B., Paranthaman M.P., Gabitto J., Prairie View A&M University, US

Anodized titanium oxide containing highly ordered, vertically oriented TiO2 nanotube arrays is a nanomaterial architecture that shows promise for diverse applications. In this paper, an anodization synthesis using HF-free aqueous solutions is described. The anodized [...]

Influence of grain’s morphology and their distribution on surface, electronic and magnetic properties of nanocrystalline Sn1-xCoxO2 Diluted Magnetic Semiconductors

Sreenivas K., Venugopal Reddy P., Osmania University, IN

With a view to understand not only the nanosize dependent properties of microstructure and electronic properties, but also to study the correlations between the surface effects associated with the magnetic nano-particles, especially the changes in [...]

Solution-processed ZnO Single Nanoparticle Transistor Using Water-based Dispersions

Wolff K., Hilleringmann U., University of Paderborn, DE

The integration of printable transistors is an issue of recent work. Different proposals base on ZnO nanoparticle inks, which have to undergo a post-deposition annealing in order to improve the film quality and burn away [...]

An Analytical Solution to a Double-Gate MOSFET with Doped Body

Agarwal N., Bandhawakar G., Amity School of Engineering & Technology, Amity University, IN

ABSTRACT A CMOS scaling is approaching the limit imposed by gate oxide tunneling. Double gate MOSFET (DGMOSFET) with undoped body has become very attractive for scaling CMOS devices down to nanometer size. Device simulation predict [...]

Selective Multiterminal Sensor on Individual ZnO Nanotetrapod

Lupan O., Chow L., Chai G., Trofim V., University of Central Florida, US

Low-cost, nonpoisonous and highly sensitive and selective sensors are needed for detection of various gases in the environment. ZnO tetrapod have potential application as chemical sensors. Our current experiments have shown that ZnO tetrapod sensor [...]

Catalyst assisted zinc oxide nanowires for gas sensors

Joshi R.K., Kumar A., University of South Florida, US

We present the room temperature detection of 100 ppm carbon monoxide using metal ( Pd and Au) decorated Zinc Oxide (ZnO) nanowires. Zin oxide nanowires were grown via Vapor Liquid Solid method whreas the palladium [...]

Strain Driven Growth of Zinc Oxide Nanowires on Sapphire: Controlling Horizontal vs. Standing Growth

Nikoobakht B., Eustis S., National Institute of Standards and Technology, US

Recently we showed large scale fabrication of field-effect transistors from horizontal ZnO nanowires (NWs) on a-plane sapphire. We are interested in understanding the factors that induce the unique growth direction of horizontal ZnO NWs and [...]

Synthesis of Self-aligned Tungsten Nanowires on Single Crystalline Tungsten Substrates

Wu W., Yu Q., Pei S-S, University of Houston, US

Metallic nanowires have attracted much attention due to their unique mechanical, magnetic, optical and electronic properties, and their function as well-defined building blocks for nanodevices.1-3 Tungsten (W), in particular, is of great interest, being promising [...]

Aluminium-Doped ZnO Films and Nanowires by a Modified Chemical Vapor Deposition Technique

Pung S.Y., Choy K.L., University of Nottingham, UK

ZnO has unique properties such as wide-bandgap (3.37eV) and large exciton binding energy (60meV) at room temperature. These properties made ZnO a promising material for short wavelength photonic devices for examples, light emitting diode (LED) [...]
