Investigation of the relationship between solar radiation and cloud cover using a total sky imager.
(2017)Solar radiometric studies have been done in South Africa, but no research studies have been performed to understand how the cloud fraction (CF) affects the amount of solar radiation received by radiometers. This work focused ... -
Characterisation and quantum application of plasmonic waveguides.
(2016)Plasmonics o ers sub-di raction confinement of light, which a ords enhanced coupling to emitter systems (e.g. quantum dots). This feature makes possible a range of on-chip quantum photonic components - most notably ... -
Characterisation of polarisation-entangled photon source for quantum key distribution.
(2016)Entanglement in real physical systems has been of great interest due to its importance in quantum mechanics. It has applications related to quantum information science speci cally quantum cryptography since it eliminates ... -

Binary and ternary molecules blend bulk heterojunction organic solar cell.
(2015)Bulk heterojunction organic solar cells were prepared and characterized in terms of electrical and optical properties of the photosensitive medium. Two cases of organic solar cells were developed in this investigation ... -
Generalisation of theory and algorithms for the configurational temperature Nosé–Hoover thermostat.
(2015)In this dissertation we reformulate the configurational temperature Nos`e-Hoover thermostat proposed by Braga and Travis (C. Braga and K.P. Travis, 2005), using the antisymmetric matrix formalism found in (A. Sergi, ... -

Single and double layer bulk heterojunction organic solar cell.
(2015)Bulk heterojunction photovoltaic device based on the binary organic comprised of P3HT:PCBM and PTB7:PCBM with weight ratio of 1:1 and 1:1.5 respectively. We used these blends as a photo-active layer with different ... -
Experimental investigation of electric-field-induced birefringence in fluids.
Measurements of the quadratic electro-optical (Kerr) effect of uids can provide knowledge of fundamental molecular properties, such as (hyper)polarizabilities. They also provide valuable information about intermolecular ... -

Stratospheric ozone climatology and variability from ground-based and satellite observations over Irene, South Africa (25.5°S; 28.1°E)
(2014)The climatological characteristic of ozone over Irene (25.˚S, 28.1˚E) was assessed in this thesis using ground-based satellite observations. The aim of this was to examine the variability of both total and vertical ozone ... -
Generation and detection of bessel beams.
(2015-09-18)In this dissertation we study the properties of Bessel-Gauss beams. Bessel-Gauss beams are created by the interference of plane waves lying on a cone, and have unique properties: they propagate without spreading and ... -
Devices for the construction of a cold atom experiment.
(2013)The experimental setup for laser cooling and trapping of 87Rb atoms with the aid of a Magneto-optical trap (MOT) is discussed. The experiment has a diverse setup, which includes: a vacuum system in which the cooling and ... -
