Domain Ordering of Strained 5ML SrTiO 3 Films on Si(001)

June 26, 2007
Author(s)
P Ryan, Joseph Woicik, D Wermeille, J.-W Kim, C S. Hellberg, H Li
We present high resolution X-ray diffraction data indicating regularly ordered square shaped coherent domains approximately 1200A in length co-existing with longer approximately 9500A correlated regions in a highly strained 5ML SrTiO3 (STO) film grown on

Margin Failures in Crown-Like Brittle Structures: Off-Axis Loading

June 11, 2007
Author(s)
Chris Ford, T Qasim, M T. Bush, X Z. Hu, Mahek Shah, Vibhu Saxena, Brian R. Lawn
The effect of off-axis loading of compliant indenters on the initiation of cracks at the margins of dental crown-like dome structures consisting of glass shells back-filled with an epoxy resin is examined. As in previous studies on similar structures but

Optical and Structural Study of GaN Nanowires Grown by Catalyst-Free MBE: (II) Defect-Related Luminescence and Electron-Beam Irradiation Effects

June 1, 2007
Author(s)
Lawrence H. Robins, Kristine A. Bertness, John G. Barker, Norman A. Sanford, John B. Schlager
GaN nanowires grown by catalyst free molecular beam epitaxy were characterized by photoluminescence (PL) and cathodoluminescence (CL) spectroscopy at temperatures from 3 K to 295 K. Both as grown samples, which contained approximately vertically oriented
