Photo-physical properties of lead-tin binary Perovskite thin films
(University of Western Cape, 2021)
Organic-inorganic lead-based perovskite has exhibited great performance in the past few years.
However, the lead (Pb) embedded in those compounds is a significant drawback to further
progress, due to its environmental ...
Silicon nanowires by metal-assisted chemical etching and its incorporation into hybrid solar cells
(University of Western Cape, 2021)
The rapid increase in global energy demand in recent decades coupled with the adverse environmental impact of conventional fuels has led to a high demand for alternative energy sources that are sustainable and efficient. ...
Variability and interannual trends in the climatology of radon-222 at two Southern Hemisphere coastal baseline sites
(University of the Western Cape, 2021)
This thesis characterises and discusses two continuous coastal Southern Hemispheric (SH) atmospheric radon (222Rn) signals. Large-scale atmospheric circulation patterns are important components of the climate system ...
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)
In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ...
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of Western Cape, 2021)
TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ...
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)
In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ...
Giant Magnetocaloric effect and Magnetic Properties of selected Rare-Earth compounds
(University of the Western Cape, 2021)
Rare-earth (RE) compounds have been an attractive subject, based on the unique electronic structures of the rare-earth elements. In particular, the RETX (RE = rare-earth, T = 3d/4d/5d, transition metals, and X = p – block ...
Triaxiality and rotational bands in 133ce
(University of Western Cape, 2021)
The neutron-de cient nuclei between the N = 50 and N = 82 shell closures provide
rich information on the shape and structure of the nucleus. The isotones of 133Ce
and 131Ba (N = 75) lie in this region of the nuclear ...
A multi-wavelength study of powerful high redshift radio galaxies
(2021)
We present a new sample of distant powerful radio galaxies, in order to study their
host-galaxy properties and provide targets for future observations of Hi absorption
with new radio telescopes. We cross-match the Sydney ...
New collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of Western Cape, 2021)
Low- and medium-spin bands of 187Os have been studied using the AFRODITE array,
following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements
of
coincidences, angular distribution ratios ...
