Hot-wire chemical vapour deposition of nanocrystalline silicon and silicon nitride : growth mechanisms and filament stability
(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 ...
TiO₂ nanotube based dye-sensitised solar cells
(University of the Western Cape, 2012)
The first report of a functioning photo-electrochemical solar cell in 1991 attracted a lot of interest from scientists and industrial groups. From an industrial point of view these so-called dye-sensitised solar cells ...
TiO2 nanotube based dye- sensitised solar cells
(University of Western Cape, 2012)
This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with
an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ...
Perturbations of dark energy models
(University of Western Cape, 2012)
The growth of structure in the Universe proceeds via the collapse of dark matter
and baryons. This process is retarded by dark energy which drives an accelerated
expansion of the late Universe. In this thesis we use ...
