Molecular Fan: A Heat Sink for Nanoelectronic Devices

Sizemore C.A., Recchia M.L., Kim T., Lin C-T, Northern Illinois University, US

Currently, electrical components are cooled by conduction of heat to a heat sink, which is cooled by convection in air. The warm air is then removed from the system using a mechanical fan. As technology [...]

Silicon Surface Modification with Silane-functionalized Polymers

Viswanathan K., Long T.E., Ward T.C., Virginia Tech, US

The synthesis of trimethoxysilane end-capped linear polystyrene (PS), star-branched PS, and subsequent silicon (Si) surface modification with the linear and star polymers are described. Trimethoxysilane terminated PS was synthesized using sec-butyl lithium initiated anionic polymerization [...]

Low Temperature Deposition of High-Quality Nanometer-Thick Dielectric Films in an Electron Cyclotron Resonance (ECR) Plasma-Enhanced CVD System

Xie L., Deng J., Shepard S., Tsakirgis J., Chen E., Harvard University, US

One of the challenges facing in nanofabrication is to deposit dielectric films with thickness compared to the feature size under fabrication, typically in a range of nanometer, for the purposes such as gate dielectrics, surface [...]

Formation of Biotinylated Alkylthiolate Self-Assembled Monolayers on Gold

Canaria C.A., Maloney J.R., Yu C-J, Smith J.O., Fraser S.E., Lansford R., California Institute of Technology, US

We demonstrate the successful formation of functional biotinylated monolayers on gold surfaces using aqueous solvents. Cyclic voltammetry (CV), alternating current voltammetry (ACV), and fluorescence microscopy have been used to characterize the films. Protein binding assays [...]

Polymer Nanocoatings by Initiated Chemical Vapor Deposition (iCVD)

Gleason K.K., Pryce Lewis H.G., Chan K., Lau K.K.S., Mao Y., Massachusetts Institute of Technology, US

Initiated chemical vapor deposition (iCVD) is a novel process capable of producing a range of polymeric and multifunctional nanocoatings. Coatings can be made extremely thin (down to 10nm) on objects with dimensions in the nanometer [...]

Multiscale Modeling of Self-Organized Mono-layer Surface Atomic Clusters

Hu Q., Ghoniem N.M., Walgraef D., University of California, Los Angeles, US

We present here a novel multiscale modeling approach to investigate the conditions for atomic cluster self-organization on atomically flat substrates during epitaxy deposition processes. A phase field model is developed for the free energy of [...]

Micromachined Nanocrystalline Silver Doped Tin Oxide Hydrogen Sulfide Sensor

Gong J., Chen Q., Lian M-R, Liu N-C, University of Central Florida, US

We report here an ultra high sensitive micromachined hydrogen sulfide gas sensor with nanocrystalline thin (100nm) silver doped SnO2 film. A polymeric sol-gel process has been successfully developed in fabricating the thin SnO2 nanofilm as [...]

Polyaniline Nanofibers and Composite Materials for Chemical Detection

Weiller B.H., Virji S., Baker C., Huang J., Li D., Kaner R.B., The Aerospace Corporation, US

Polyaniline is a conducting polymer with electrical properties that can change greatly upon exposure to various chemicals. Most notably, when polyaniline is exposed to strong acids and bases, the conductivity changes by greater than 8 [...]

Nanostructured Gas Microsensor Platform

Routkevitch D., Polyakov O., Deininger D., Kostelecky C., Synkera Technologies, Inc., US

Nanostructured materials, with their small grain size, large number of grain boundaries, and high specific surface area, hold promise for significantly improving the performance of solid-state gas sensors. To fully realize this potential, precision nanoscale [...]

Frequency Stability and Noise Characteristics of Ultra-High Frequency (UHF) Nanoelectromechanical Resonators

Feng X.L., Roukes M.L., California Institute of Technology, US

Nanoelectromechanical systems (NEMS) are emerging as great candidates for a variety of technological applications ranging from sensors and actuators to signal processing and communications [1]. Nanofabricated high-frequency (often in the VHF/UHF bands) electromechanical resonators (i.e., [...]
