  • Micro-Raman spectroscopy of nanomaterials : applications in Archaeology 
    Prinsloo, Linda Charlotta (University of Pretoria, 2009-06-02)
    “Nanomaterials” is a generic term used to describe nano-sized crystals and bulk homogenous materials with a structural disorder at the nanoscale. Ancient (and modern) ceramics and glasses derive some of their properties ...
  • Optical characterization of semiconductors using photo reflection spectroscopy 
    Sieberhagen, Rheinhardt Hendrik (University of Pretoria, 2006-11-30)
    The study of semiconductor materials and more recently, artificially struc¬tured materials, is important for both scientific and industrial purposes. Many techniques have been developed to characterize the electronic ...
  • An optical investigation of implantation damage as GaAs superlattices 
    Haile, Kibreab Mebrahtom (University of Pretoria, 2006-05-05)
    In this work tunability, implantation damage and recovery of GaAs doping superlattices implanted with hydrogen ions were studied. The applicability of two models of the optical properties of semiconductors was also ...
