Metal assisted chemically etched silicon nanowires for application in a hybrid solar cell
(University of the Western Cape, 2018)
Photovoltaic (PV) devices based on inorganic-organic hybrid active layers have been
extensively studied for over a decade now. However, photoactive hybrid layers of
material combinations such as rr-P3HT and SiNWs still ...
Development and study of a Thoron (Rn-220) standard source
(University of Western Cape, 2019)
Thoron Rn-220 is a radioactive gas with a half-life of 55.6 s. It has been identified as a possible health concern in specific places such as monazite processing plants and (rare-earth) mines. The short half-life of Rn-220 ...
Polarizability effects due to low-energy enhancement of the gamma-strength function
(University of the Western Cape, 2018)
Physics is the study of natural phenomena. Nuclear physicists have since the
discovery of the nucleus been working on understanding its dynamics. The nuclear
chart, analogous to the periodic table of elements, is illustrated ...
Measuring transitional matrix elements using first-order perturbation theory in Coulomb excitation
(University of the Western Cape, 2019)
The aim of nuclear structure physics is to study the interplay between singleparticle
and collective degrees of freedom in nuclei and to explain how nuclei
get excited and decay under di erent external conditions, such ...
Design of a helium-6 production target for the iThemba LABS Radioactive-ion Beam Facility
(University of the Western Cape, 2018)
It is well known, that there is a severe lack of information available pertaining to neutron rich nuclei, specifically of those nuclei with mass numbers ≥ 60. These neutron rich nuclei are not easy to access in current ...
Magnetocaloric effect and critical behaviour near the magnetic phase transition temperature in rare-earth compounds
(University of the Western Cape, 2018)
Rare-earth intermetallic compounds continue to draw considerable attention, due to
their fundamental importance in understanding physical properties and potential applications
based on a variety of phenomena. The focus ...
Detecting Galaxies in the Epoch of Reionization
(University of the Western Cape, 2017)
The aim of this project was to develop a technique that allows us to measure the redshift
of radio galaxies in the Epoch of Reionization. We achieved this by constructing
a parameterization of the 21-cm absorption feature ...
Coupling of single neutron configurations to collective core excitations in 162Yb using 163Yb
(University of the Western Cape, 2017)
In odd-nuclei the single nucleon can couple to collective excitations of its even-even core
nucleus . These collective excitations lie within the pairing gap and are therefore the
lowest energy excitations of the core. Our ...
Point source simulations and Foreground cleaning techniques for HI intensity mapping
(University of the Western Cape, 2018)
We created a full sky point source catalogue at frequencies around 1 GHz, including
the intensity, polarisation, rotation measure and spectral index of the point source.
These values were matched to data where available ...
Galaxy Clustering as a Probe for Galaxy Evolution in Simulations
(University of the Western Cape, 2017)
Studying clustering on small scales (<10Mpc) over a large span of red-
shifts allows us to connect galaxies to underlying cosmic large-scale
structure, and thereby provide constraints on the physical processes
that drive ...
