S and Si Ion-Implantation in GaSb Grown on GaAs

December 1, 1999
Author(s)
M V. Rao, A K. Berry, T Q. Do, M C. Ridgway, P Chi, J Waterman
Single and multiple energy S and Si ion-implantations were performed at room temperature (RT) and at 200 C into GaSb epitaxial layers grown on semi-insulating GaAs substrates. The implanted material was annealed with a Si 3N 4 cap at 400-600 C for 5 min

Scotch Pine Christmas Tree Fire Tests. REPORT OF TEST FR 4010

December 1, 1999
Author(s)
D W. Stroup, Laurean A. DeLauter, Jack C. Lee, G Roadarmel
A series of fire tests were conducted to characterize the potential hazard from ignition of Scotch Pine Christmas trees. Heat release rate was measured as a function of time from ignition using a large calorimeter. In addition, radiative flux and total

Size Change of Dendrimers in Concentrated Solution

December 1, 1999
Author(s)
A Topp, Barry J. Bauer, T J. Prosa, R L. Scherrenberg, Eric J. Amis
Solutions of the poly(propylene imine) dendrimers DAB-dendr-(NH 2) 23 and DAB-dendr-(NH 2) 64 in methanol are investigated with small angle neutron scattering over the range of dendrimer mass fraction 0.01# x # 0.80. The single particle scattering function

Study of Ethylene-Propylene Copolymer Thermoreversible Gels

December 1, 1999
Author(s)
C Daniel, T C. Jao, Barry J. Bauer, Eric J. Amis
Molecular structure and rheological properties of ethylene-propylene (EP) random copolymer gels formed in toluene and methylcyclohexane, respectively, have been investigated by small angle neutron scattering (SANS) and oscillatory shear. In both solvents
