Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ... -
Chemical pressure-induced transition of the magnetic ground state from ferromagnetic to antiferromagnetic order in CeCuGe and DyCuIn alloys
(University of the Western Cape, 2023)Rare-earth intermetallic compounds continue to attract considerable attention, due to their fundamental importance in understanding physical properties and potential applications based on a variety of phenomena. The ternary ... -
Accelerating reionization simulations using machine learning
(University of the Western Cape, 2023)Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ... -
Physics graduate preparedness for work and society
(University of the Western Cape, 2023)Both internationally and in South Africa, there have been renewed debates about the purposes of higher education and the attributes that should be developed in graduates. In the field of physics, many studies have reported ... -
Machine learning approaches to study star formation and black hole accretion in the Meerkat/MIGHTEE survey
(University of the Western Cape, 2023)Galaxy formation and evolution are driven by two main physical processes: star formation and black hole accretion. Both processes can be traced via the synchrotron emission at radio wavelengths. However, a reliable ... -
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ... -
A case study of university students' experiences of introductory physics drawn from their approaches to problem solving
(University of the Western Cape, 2001)This thesis explores the experience of leaming physics through a particular medium: problem-solving, which is seen by many educators as the primary medium in which physics is learnt at university. Situating itself within ... -
Study of the use of Electret Ion chambers as radom dosimeters in South Africa
(University of the Western Cape, 2002)Radon is a naturally occuring radioactive gas which has been shown to be a major contribution to background dose. The underground mines in South Africa present a major occupational hazard. A need for cheap personal monitoring ... -
