• Nanoscale mapping of optical band gaps using monochromated Electron Energy Loss Spectroscopy 

      Zhan, Wei; Granerød, Cecilie Skjold; Venkatachalapathy, Vishnukanthan; Johansen, Klaus Magnus H; Jensen, Ingvild Julie Thue; Kuznetsov, Andrej; Prytz, Øystein (Peer reviewed; Journal article, 2017)
      Using monochromated electron energy loss spectroscopy in a probe-corrected scanning transmission electron microscope we demonstrate band gap mapping in ZnO/ZnCdO thin films with a spatial resolution below 10 nm and spectral ...
    • Vertical GaN nanocolumns grown on graphene intermediated with a thin AlN buffer layer 

      Liudi Mulyo, Andreas; Rajpalke, Mohana Krishnappa; Kuroe, Haruhiko; Vullum, Per-Erik; Weman, Helge; Fimland, Bjørn-Ove; Kishino, Katsumi (Peer reviewed; Journal article, 2018)
      We report on the self-assembled growth of high-density and vertically-oriented n-doped GaN nanocolumns on graphene by radio-frequency plasma-assisted molecular beam epitaxy. Graphene was transferred to silica glass, which ...
