Nanoelectronic Devices Constructed Using Individual Vertically Aligned Carbon Nanofibers

Yang X., Austin D.W., Guillorn M.A., Merkulov V.I., Melechko A.V, Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We are fabricating active nanoscale electronic devices based on Vertically Aligned Carbon Nanofibers (VACNF). VACNFs are synthesized in a high-density Plasma-Enhanced Chemical Vapor Deposition (PECVD) process that provides a high degree of control of the [...]

Nano-sensors Based on Nanotubes: Deformed-nanotubes transport

Farajian A.A., Yakobson B.I., Mizuseki H., Kawazoe Y., Tohoku University, JP

The main purpose of the present work is to establishing a correspondence between mechanical deformation and transport properties, which is presumably useful in nano-sensor applications. As a byproduct of this study, the potential differences in [...]

CB Nanosensors

Jarvis N.L., Snow A.W., Wohltjen H., Smardzewski R.R., Edgewood Chemical & Biological Center, US

A new class of nanometer-scale, low power, solid-state devices is being investigated for the detection of hazardous vapors. These chemical vapor sensors are comprised of nanometer-sized gold particles encapsulated by monomolecular layers of alkanethiol surfactant [...]

Self-Heating Effects in GaN/AlGaN Heterostructure Field-Effect Transistors and Device Structure Optimization

Filippov K.A., Balandin A.A., University of California Riverside, US

In this paper we present results of our simulation of temperature rise in GaN/AlGaN HFETs characterized by different geometry, layered structure, doping density and substrate type. We do note make simplifying assumptions of the uniform [...]

Multi-Tunnel-Junction Memory : Analyses of Feasibility for Non-Volatile Memory Applications

Le Carval G., Le Royer C., Le Carval G., Le Royer C., Sanquer M., CEA-LETI, FR

MOSFET Memories based on quantum dots have been investigated extensively because of their promising applications to non-volatile and low voltage memories. Among these memories, the Multi-Tunnel-Junction Memory (MTJM) appears to be a promising concept for [...]

High Order Parametric Resonance and Nonlinear Mechanics of Nanowires: Techniques and Experiments

Yu M-F, Wagner G.J., University of Illinois at Urbana-Champaign, US

We realize parametric resonances in a nanowire mechanical system using an oscillating electric field. The realization of high order parametric mechanical resonance in macroscopic systems is generally difficult due to mechanical energy losses and strict [...]

An Improved Single-Electron-Transistor Model for SPICE Application

Wu Y-L, Lin S-T, National Chi-Nan University, TW

Single electron transistors (SETs) have drawn much attention of researchers and scientists because they are considered candidate as one of the elements for future low power, high-density memories and logic circuits. Instead of using Monte [...]

Single-molecule Fluorescence and Force Microscopy Employing Carbon Nanotubes

Wade L.A., Shapiro I., Ma Z., Quake S.R., Collier C.P., California Institute of Technology, US

The observation of spectroscopic signals, in response to mechanically induced changes in biological macromolecules can be enabled at an unprecedented level of resolution by coupling single-molecule manipulation/sensing using carbon nanotubes with single-molecule fluorescence imaging. Proteins, [...]

Nano-Electronic Sensors – Practical Device Designs for Sensors

Stetter J.R., Bradley K., Cumings J., Gabriel J-C, Gruner G., Star A., Nanomix, US

There is often a large gap between laboratory science and practical products. It will take some years to fathom the overall technical importance of nano-technology and even longer to realize societal benefits through practical products. [...]

Novel Random Number Generators Based on Si Nanodevices for Mobile Communication Security Systems

Fujita S., Uchida K., Yasuda S., Ohba R., Tanamoto T., Toshiba Corp, JP

We propose a new application of silicon (Si) nanodevices that can generate high-quality random numbers (HQ-RNs) for mobile communication security systems, one of most important elements of information technology (IT). We have successfully demonstrated the [...]
