  • Kucheyev, Sergei; Toth, Milos; Williams, Jim; Jagadish, Chennupati; Li, Gang; Phillips, Matt (American Institute of Physics, 2001)
  • Kucheyev, Sergei; Toth, Milos; Williams, Jim; Jagadish, Chennupati; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    The influence of ion-beam-produced lattice defects as well as H, B, C, N, O, and Si, introduced by ion implantation, on the luminescence properties of wurtzite GaN is studied by cathodoluminescence spectroscopy. Results ...
  • Bradby, Jodie; Kucheyev, Sergei; Williams, Jim; Jagadish, Chennupati; Swain, Michael; Munroe, Paul; Phillips, Matt (American Institute of Physics, 2002)
    Contact-induced damage has been studied in single-crystal (wurtzite) ZnO by cross-sectional transmission electron microscopy (XTEM) and scanning cathodoluminescence (CL) monochromatic imaging. XTEM reveals that the prime ...
  • Mokkapati, Sudha; Lever, Penelope; Tan, Hark; Jagadish, Chennupati; Mcbean, Katie; Phillips, Matt (Amer Inst Physics, 2005)
    Selective growth of InGaAs quantum dots on GaAs is reported. It is demonstrated that selective-area epitaxy can be used for in-plane bandgap energy control of quantum dots. Atomic force microscopy and cathodoluminescence ...

  • Coleman, V; Buda, M; Tan, Hark; Jagadish, Chennupati; Koike, K; Sasa, S; Inoue, M; Yano, M; Phillips, Matt (IOP Publishing Ltd, 2006)
    Implantation with low-energy (80 keV) oxygen ions and subsequent rapid thermal annealing at 800 degrees C are used to induce intermixing in a stack of 19 ZnO/Zn0.7Mg0.3O multiple quantum wells grown oil sapphire by molecular ...
  • Coleman, Va; Bradby, Jodie; Jagadish, Chennupati; Phillips, Matt (Amer Inst Physics, 2006)
    The influence of spherical nanoindentation on the band edge and deep level emission of single crystal c-axis ZnO has been studied by cathodoluminescence (CL) spectroscopy and monochromatic imaging. Excitonic emission is ...
  • Mokkapati, Sudha; Wong-Leung, Jennifer; Tan, Hark; Jagadish, Chennupati; Mcbean, Katie; Phillips, Matt (IOP Publishing Ltd, 2008)
    In-plane bandgap energy control of InAs quantum dots (QDs) grown on GaAs substrates is demonstrated using selective-area epitaxy. Transmission electron microscopy and cathodoluminescence are used for characterization of ...
  • Kucheyev, Sergei; Toth, Milos; Williams, Jim; Jagadish, Chennupati; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    Electrical isolation of n-type GaN epilayers bombarded with MeV light ions is studied by energy dispersive x-ray spectrometry (EDS). We show that the maximum bremsstrahlung x-ray energy (the Duane-Hunt limit) can be used ...
