Filament carburization during the hot-wire chemical vapour deposition of carbon nanotubes
Oliphant, Clive Justin (University of the Western Cape, 2008)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. -
Hot-wire chemical vapour deposition of nanocrystalline silicon and silicon nitride : growth mechanisms and filament stability
Oliphant, Clive Justin (University of the Western Cape, 2012)Nanocrystalline silicon (nc-Si:H) is an interesting type of silicon with superior electrical properties that are more stable compared to amorphous silicon (a-Si:H). Silicon nitride (SiNₓ) thin films are currently the ...
