Fabrication and characterization of a solar cell using an aluminium p-doped layer in the hot-wire chemical vapour deposition process
Lebogang, Kotsedi (2010)When the amorphous silicon (a-Si) dangling bonds are bonded to hydrogen the concentration of the dangling bond is decreased. The resulting film is called hydrogenated amorphous silicon (a-Si:H). The reduction in the dangling ... -

Optical modeling of amorphous and metal induced crystallized silicon with an effective medium approximation
Muller, Theophillus Frederic George (University of the Western Cape, 2009)In this thesis we report on the metal-mediated-thermally induced changes of the structural and optical properties of hydrogenated amorphous silicon deposited by hot-wire CVD, where aluminium and nickel were used to induce ... -
A study of hydrogenated nanocrystalline silicon thin films deposited by hot-wire chemical vapour deposition (HWCVD)
Halindintwali, Sylvain (University of the Western Cape, 2005)In this thesis, intrinsic hydrogenated nanocrystalline silicon thin films for solar cells application have been deposited by means of the hot – wire chemical vapour deposition (HWCVD) technique and have been characterised ... -
Towards stimuli-responsive functional nanocomposites: smart tunable plasmonic nanostructures Au-VO2
Kana, Jean Bosco Kana (University of the Western Cape, 2010)The fascinating optical properties of metallic nanostructures, dominated by collective oscillations of free electrons known as plasmons, open new opportunities for the development of devices fabrication based on noble metal ...
