Thermal Expansion of Morphologically Textured Short-Fiber Composites

January 1, 1999
Author(s)
Martin Dunn, H M. Ledbetter, Z Li
We studied, both experimentally and theoretically, the thermoelastic response of short-fiber composites with a preferred orientation of the short fibers, i.e., a morphological texture. Our theoretical efforts are general, being applicable to any composite

Tip Characterization for Dimensional Nanometrology

January 1, 1999
Author(s)
John S. Villarrubia
Technological trends are increasingly requiring dimensional metrology at size scales below a micrometer. Scanning probe microscopy has unique advantages in this size regime, but width and roughness measurements must be corrected for imaging artifacts. This

Tomographic Reconstruction of an Integrated Circuit Interconnect

January 1, 1999
Author(s)
Zachary H. Levine, A R. Kalukin, S P. Frigo, I McNulty, M Kuhn
An Al-W-silica integrated circuit interconnect sample was thinned to several micro υ and scanned across a 200 nm focal spot of a Fresnel zone plate operating at photon energy of 1573 eV. The experiment was performed on beamline 2-ID-B of the Advanced

Total Electron Scattering Cross Section for Cl 2

January 1, 1999
Author(s)
Gary D. Cooper, Jason E. Sanabia, J. H. Moore, James K. Olthoff, Loucas G. Christophorou
Absolute measurements of the total electron scattering cross section for chlorine, Cl2, are reported for electron energies ranging from .3 eV to 23 eV. The present data are in reasonable agreement with previous measurements of the cross sections for total

Toward a National Standards Strategy to Meet Global Needs

January 1, 1999
Author(s)
W G. Leight, K J. Leuteritz
On September 23, 1998, the National Institute of Standards and Technology (NIST) and the American National Standards Institute (ANSI) co-hosted a summit conference, Toward a National Standards Strategy To meet Global Needs. NIST Director Ray Kammer and

Trapping and Cooling of Potassium Isotopes in a Double-Magneto-Optical-Trap Apparatus

January 1, 1999
Author(s)
M Prevedelli, F S. Cataliotti, Eric A. Cornell, J R. Ensher, C Fort, L Ricci, G M. Tino, M Inguscio
We report on teh efficient operation of a double-magneto-optical-trap (MOT) apparatus for potassium isopes. Mechanisms for the cooling and the transfer between the two MOTs are studied. A magnetic quadrupole trap has been loaded from the second MOT
