Journal ArticleDOI
Observation of Negative Magnetic Hysteresis Loop in ZnO Thin Films
Micah Haseman,Pooneh Saadatkia,David Winarski,Armando Hernandez,Matt Kusz,Wolfgang Anwand,Andreas Wagner,Sunil Thapa,Anthony Colosimo,Farida Selim +9 more
TL;DR: In this paper, an unusual negative magnetic hysteresis loop was observed in ZnO thin film codoped with cobalt and aluminum (Co-Al:ZnO).
Journal ArticleDOI
Residual Stress Measurements in Welded and Plastically Deformed Target Structural Materials
Ajit K. Roy,Anand Venkatesh,Satish Dronavalli,Vikram Marthandam,Douglas P. Wells,Farida Selim,Ronald Rogge +6 more
TL;DR: In this article, the structural material (Type 304L stainless steel/Alloy EP-823) surrounding the transmutation target will be subjected to welding operation and plastic deformation during fabrication, which could induce residual stresses in it.
Journal ArticleDOI
Interface effect of Fe and Fe2O3 on the distributions of ion induced defects
Hyo-Sung Kim,Matthew Chancey,T. R. Chung,I. D. Brackenbury,Maciej Oskar Liedke,Maik Butterling,Eric W. Hirschmann,Andreas Wagner,Jon K. Baldwin,Benjamin Derby,Nan Li,Kayla Yano,Danny J. Edwards,Yongqiang Wang,Farida Selim +14 more
TL;DR: In this paper , depth-resolved positron annihilation lifetime spectroscopy (PALS) and complementary transmission electron microscopy (TEM) were used to investigate small-scale defects created by ion irradiation in an epitaxially grown (100) Fe film capped with a 50 nm Fe2O3 oxide layer.
Book ChapterDOI
Trap Level Measurements in Wide Band Gap Materials by Thermoluminescence
TL;DR: In this paper, an advanced wavelength-based thermoluminescence (TL) spectrometer is presented, and its applications for the evaluation of trap levels and the characterization of donors and acceptors in semiconductors and dielectrics are discussed.
Journal ArticleDOI
In-flight annihilation during positron channeling
Alan W. Hunt,Alan W. Hunt,David Cassidy,David Cassidy,Farida Selim,R. Haakenaasen,Thomas E. Cowan,Richard H. Howell,Kelvin G. Lynn,J. A. Golevchenko +9 more
TL;DR: In this paper, the channeling effects on in-flight annihilation radiation from positrons traversing a thin gold crystal were investigated and it was shown that two-photon annihilation is significantly enhanced compared to single photon annihilation due to the selective interaction of well-channeled positrons with valence electrons in the interstitial regions of the crystal.
