    Filament carburization during the hot-wire chemical vapour deposition of carbon nanotubes
    (University of the Western Cape, 2008) Oliphant, Clive Justin; Arendse, C.J.; Knoesen, Dirk; Dept. of Physics; Faculty of Science
    This study reports on the changes in the structural properties of a tungsten-filament when exposed to a methane / hydrogen ambient for different durations at various filament-temperatures.

    Metal oxide nanocrystalline thin films as buffer layers in organic/ hybrid solar cells
    (University of Western Cape, 2019) Bowers, Norman Mark; Muller, T.F.G.; Arendse, C.J.
    Without reverting to encapsulation, organic bulk - heterojunction solar cells can be protected from the oxidation of the highly reactive low work function cathode metal electrode, by the deposition of metal oxide buffer layers onto an indium-tin oxide (ITO) substrate. The zinc-oxide (ZnO) or titanium dioxide (TiO2) layer can serve as an electron collecting contact. In such a case the ordering of layer deposition is inverted from the traditional layer sequencing, using an additional effect of the metal oxide layer acting as a hole blocking contact
