Experimental separability of channeling giant magnetoresistance in Co/Cu/Co

July 13, 2006
Author(s)
William E. Bailey, Stephen E. Russek, X.-G. Zhang, W. H. Butler
The magnitude of the electronic channeling contribution is a significant open issue in the understanding of giant magnetoresistance (GMR). We show that for the technologically important system Co/Cu/Co, channeling GMR can be isolatedand quantified

Cement Hydration: Building Bridges and Dams at the Microstructure Level

July 12, 2006
Author(s)
Dale P. Bentz
The concurrent goals of cement hydration are to percolate (bridge) the original cement particles into a load-bearing network and to depercolate (dam) the original water-filled capillary porosity. The initial volume, particle size distribution, and

Mapping substrate/film adhesion with contact-resonance-frequency AFM

July 12, 2006
Author(s)
Donna C. Hurley, Malgorzata Kopycinska-Mueller, Eric Langlois, Tony B. Kos, Nicholas Barbosa
We demonstrate contact-resonance-frequency atomic force microscopy (AFM) techniques to nondestructively image variations in adhesion at a substrate/film interface. Contact-resonance-frequency imaging is a dynamic AFM technique to measure the contact

Mapping substrate/film adhesion with contact-resonance-frequency atomic force microscopy

July 12, 2006
Author(s)
Donna C. Hurley, M Kopycinski-Muller, Eric Langlois, Anthony B. Kos, N. Barbosa
We have used contact-resonance-frequency atomic force microscopy techniques to nondestructively image variations in adhesion as a buried interface. Images were acquired on a sample containing a 20nm gold (Au) blanket film on silicon (Si) with a 1 nm

Supplementary Backward Equations for Pressure as a Function of Enthalpy and Entropy p(h,s) to the Industrial Formulation IAPWS-IF97 for Water and Steam

July 11, 2006
Author(s)
H J. Kretzschmar, J Cooper, A Dittmann, J Trubenbach, Th Willkommen, Daniel G. Friend, J S. Gallagher, Radim Mares, Kiyoshi Miyagawa, Wolfgang Wagner, K Knobloch, I. Stocker
In 2001, the International Association for the Properties of Water and Steam (IAPWS) adopted backward equations for pressure as a function of enthalpy and entropy p(h, s) as supplement to the IAPWS Industrial Formulation 1997 for the Termodynamic

Vortices in Attractive Bose-Einstein Condensates in Two Dimensions

July 7, 2006
Author(s)
L D. Carr, Charles W. Clark
The form and stability of quantum vortices in Bose-Einstein condensates with attractive atomic interactions is elucidated. They appear as ring bright solitons, and are a generalization of the Townes soliton to nonzero winding number m. An in?nite sequence

Effect of Self-Assembled Monolayer Film Order on Nanofriction

July 6, 2006
Author(s)
S Sambasivan, S Hsieh, Daniel A. Fischer, Stephen M. Hsu
Friction at the nanoscale has become a significant challenge for microsystems, including MEMS, NEMS and other devices. At nanoscale, lateral loading often causes component breakage and loss of functions in devices, therefore, accurate measurement and

Semiconductor Microelectornics and Nanoelectronics Programs

July 5, 2006
Author(s)
Stephen Knight, Joaquin (. Martinez, Michele L. Buckley
The microelectronics industry supplies vital components to the electronics industry and to the U.S. economy, enabling rapid improvements in productivity and in new high technology growth industries such as electronic commerce and biotechnology. The

Simulations of Optical Microscope Images

July 3, 2006
Author(s)
Thomas A. Germer, Egon Marx
The resolution of an optical microscope is limited by the optical wavelengths used. However, there is no fundamental limit to the sensitivity of a microscope to small differences in any of a feature's dimensions. That is, those limits are determined by
