High Degree of Crystalline Perfection in Spontaneously Grown GaN Nanowires

January 1, 2006
Author(s)
Kristine A. Bertness, Alexana Roshko, Albert Davydov, Igor Levin, Mark D. Vaudin, Joy Barker, John B. Schlager, Norman Sanford, Larry Robins
We have grown a variety of isolated GaN nanowires using gas-source molecular beam epitaxy (MBE) and characterized their structural and optical properties. The nanowires have demonstrated a number of promising materials characteristics, including low defect

High Rate Tensile Strength Measurements of Frangible Bullets Using a Kolsky Bar

January 1, 2006
Author(s)
S P. Mates, Richard L. Rhorer, S Banovic, Eric P. Whitenton, Richard J. Fields
The tensile strength of frangible bullets is measured by a high rate diametral compression test (DCT) performed with a Kolsky Bar. Frangible bullets, meant to disintegrate on impact by brittle failure, also exhibit significant plasticity in compression. As

High Throughput Measurement of Peel of a Pressure Sensitive Adhesive

January 1, 2006
Author(s)
P M. McGuiggan, James J. Filliben
The peel force of a pressure sensitive adhesive (PSA) tape is measured on a surface that varied linearly in temperature. As the tape is peeled from the surface, the adhesive is peeled from a surface at a different temperature. The temperature can be
