Layer Perfection in Ultrathin InAS Quantum Wells in GaAs(001)

January 1, 2000
Author(s)
J A. Gupta, S P. Watkins, E D. Crozier, Joseph Woicik, D A. Harrison, D Jiang, I J. Pickering, B A. Karlin
X-ray diffraction (XRD), X-ray standing wave (XSW) and X-ray absorption fine structure (XAFS) measurements were used to assess the layer perfection and positions of 1 and 2 monolayer (ML) InAs quantum wells buried in GaAs(001). Photoluminescence (PL)

Load History Dependence of Fracture in Rubber-Toughened Epoxies

January 1, 2000
Author(s)
Donald L. Hunston, J He, R Raghavan, D Hoffman
It is well know that the most common toughening mechanisms in structural adhesives are viscoelastic processes so the fracture energies for bulk adhesive specimens and bonded joints vary with loading history. The work here examines this effect by measuring

Magnetic Trapping of Neutrons

P R. Huffman, C R. Brome, J S. Butterworth, K Coakley, Maynard S. Dewey, S N. Dzhosyuk, R G. Golub, G L. Greene, K Habicht, Steve K. Lamoreaux, C E. Mattoni, D N. McKinsey, Fred E. Wietfeldt, John M. Doyle

Matrix Clusters and Polymer-Matrix Adducts in the MALDI Analysis of Polystyrene

January 1, 2000
Author(s)
R J. Goldschmidt, Charles M. Guttman
The formation of matrix cluster ions and of polymer-matrix adduct ions in the matrix-assisted laser desorption/ionization (MALDI) analysis of polystyrene was investigated using layered sample preparations. It has been shown by post-source decay (PSD)
