Fabrication and Analysis of GaN Nanorods grown by MBE

January 1, 2005
Author(s)
Norman Sanford, Larry Robins, Matthew H. Gray, J E. Van Nostrand, C Stutz, R Cortez, Albert Davydov, Alexander J. Shapiro, Igor Levin, Alexana Roshko
GaN nanorods were grown on c-plane sapphire substrates under N-rich conditions by plasma-assisted molecular-beam epitaxy. Scanning electron microsopy revealed densely packed nanorods of hexagonal cross section with diameters ranging from roughly 40 to 100

Feshbach Resonances in Fermionic 6 Li

January 1, 2005
Author(s)
C H. Schunck, M W. Zwierlein, C A. Stan, S M. Raupach, W Ketterle, Andrea Simoni, Eite Tiesinga, Carl J. Williams, Paul S. Julienne

Flammability of Nanocomposites-Effects of the Shape of Nanoparticles

January 1, 2005
Author(s)
Takashi Kashiwagi
Nanocomposites based on three different shapes of nanoscale particles, sphere (silica), plate (clay), and tube (carbon nanotube), were prepared and the dispersion of the particles in the nanocomposites was confirmed by various techniques using TEM, SEM

Flammability Properties of Polymer Nanocomposites with Single-Walled Carbon Nanotubes: Effects of Nanotube Dispersion and Concentration

January 1, 2005
Author(s)
Takashi Kashiwagi, F Du, K Winey, K M. Groth, John R. Shields, S Bellayer, H J. Kim, Jack F. Douglas
The effects of the dispersion and concentration of single walled carbon nanotube (SWNT) on the flammability of polymer/SWNT nanocomposites were investigated. The polymer matrix was poly (methyl lmethacrylate) (PMMA) and the SWNT were dispersed using a

Frequency Stability, ed. by K. Chang

January 1, 2005
Author(s)
David A. Howe
This chapter introduces the concept of frequency stability measurements of oscillators by the Allan Deviation and spectral analysis. Examples and typical results are presented. Physical interpretations of common noise processes are discussed.

Fundamental limits in fiber Bragg grating peak wavelength measurements

January 1, 2005
Author(s)
Shellee D. Dyer, Paul A. Williams, Robert J. Espejo, Jonathan Kofler, Shelley M. Etzel
We discuss the fundamental limits of fiber Bragg grating (FBG) wavelength metrology. High-accuracy wavelength measurements are critical for FBG strain sensors, because wavelength measurement uncertainties even as small as 1 pm lead to an uncertainty of
