  • Effects of high temperature annealing on single crystal ZnO and ZnO devices 
    Mtangi, Wilbert; Auret, Francois Danie; Diale, M. (Mmantsae Moche); Meyer, Walter Ernst; Chwanda, Albert; De Meyer, Hannes; Janse van Rensburg, Pieter Johan; Nel, Jacqueline Margot (American Institute of Physics, 2012-04-16)
    We have systematically investigated the effects of high-temperature annealing on ZnO and ZnO devices using current voltage, deep level transient spectroscopy (DLTS) and Laplace DLTS measurements. Current–voltage measurements ...
  • Introduction and annealing of primary defects in proton-bombarded n-GaN 
    Schmidt, Matthias; De Meyer, Hannes; Jansen van Rensburg, P.J.; Meyer, Walter Ernst; Auret, Francois Danie (Wiley, 2014-01)
    We report on in situ space charge spectroscopy measure-ments on low-temperature 1.6 MeV proton-bombarded n-type gallium nitride thin film samples. The scope of this study was to investigate the introduction and annealing ...
  • Observation of low-temperature annealing of a primary defect in gallium nitride 
    Schmidt, Matthias; Janse van Rensburg, Pieter Johan; De Meyer, Hannes; Meyer, Walter Ernst; Auret, Francois Danie (Elsevier, 2014-04)
    Primary defects were introduced into n-type gallium nitride (GaN) thin films by 1.6 MeV-proton bombardment at 20 K. The electronic states of these defects were investigated by means of optical space charge spectroscopy. ...
