Germanium antimony sulphide nano wires fabricated by chemical vapour deposition and e-beam lithography

Huang C-C, Tai C-Y, Liu C-J, Simpson R.E., Knight K., Hewak D.W., University of Southampton, UK

Germanium antimony sulphide (Ge-Sb-S) amorphous thin films and nano wires have been directly deposited and patterned on SiO2-on-silicon substrates by means of chemical vapour deposition, e-beam lithography and dry etching. The Ge-Sb-S thin films were [...]

OH Radical Oxidation of Ethylene Adsorbed on Graphene: A Quantum Chemistry Study

Iuga C., Vivier-Bunge A., Universidad Autónoma Metropolitana, MX

The functionalization of carbon based nanomaterials could have applications in atmospheric chemistry and contaminants removal. In this work, a quantum chemistry and computational kinetics study has been performed on the OH radical addition to ethylene [...]

Low Turn-On Voltage and High Focus Capability Nanogaps for Field Emission Displays

Kuo Y-T, Lo H-Y, Li Y., National Chiao Tung University, TW

Nanometer scale gaps (nanogaps) has been wildly used as electrode in molecular electronics [1,2], biosensor [3], and vacuum microelectronics [4]. However, the difficult from the fabrication limits the development of such technique until the surface [...]

Nanostimulation in Brain and Emerging Imaging Capabilities

Sharma A., Sharma R., Sharma A., Sharma R., MP Agriculture and Engineering University, IN

With advent of nanoscale imaging technology available, possibly this dilemma may be solved by fusion of microimaging techniques like MRI/PET/CT/SPECT using smart imaging contrast materials.

Modeling and Analysis of a Membrane-Based Randomized-Contact Decoder

Long J., Savage J.E., Brown University, US

Controlling nanowires with mesoscale wires is important in addressing nanoscale memories. In this paper we report on simulations and analysis of an implementation of the randomized-contact decoder that is based on the use of porous [...]

Implementation of Comparison Function Using Quantum-Dot Cellular Automata

Wagh M.D., Sun Y., Annampedu V., Lehigh University, US

Quantum-Dot cellular automata (QCA) architectures represent the future of computing. But it can only implement an inverter and a three input majority gate directly. Consequently very few QCA architectures are available in literature. By fixing [...]

Logicless Computational Architectures with Nanoscale Crossbar Arrays

Mouttet B., George Mason University, US

Modern computational architectures are reliant on basic logic circuits carrying out Boolean operations such as AND, OR, XOR, etc. Recently efforts have been made to replicate the functions of such logic circuits using various nanoelectronic [...]

Multi-Bit/Cell SONOS Flash Memory with Recessed Channel Structure

Han K-R, Kwon H-I, Lee J-H., Kyungpook National University, KR

A novel device structure for 4-bit/cell with recessed channel structure is presented and characterized for NOR-type nonvolatile memory (NVM) technology. In this paper, we studied a 4-bit/cell SONOS flash memory cell Since two transistors in [...]

Polypyrrole nanoionic composites for solid state electronics

Zhao J.H., Pillai R.G., Freund M.S., Thomson D.J., University of Manitoba, CA

In this report, a conjugated semiconducting polymer composite was designed to have a mobile charge carrier density that can be controlled through an electric field. An electrochemically deposited polypyrrole (PPy) composite between two gold electrodes [...]

Optical absorption and luminescence study of ZnS quantum dots

Chakdar D., Gope G., Talukdar A., Avasthi D.K., Nath S.S., Research Scholor, IN

We report here ZnS quantum dots synthesized by chemical method at room temperature. In this technique ZnS quantum dots are produced by simple chemical reactions where Zeolite, acting as matrix, plays the key role in [...]
