This study presents a model of the hydrogen atom for the orbital angular momentum l = 1 and l = 3 using the causal interpretation also referred to as the Bohm-de Broglie interpretation of quantum mechanics. The causal interpretation is an alternative interpretation of quantum mechanics that gives...

The optical investigation of tungsten diphosphide (WP2), a type-II Weyl semimetal, reveals its exceptional topological and anisotropic electronic properties. Through resistivity and Fourier-transform infrared spectroscopy measurements, WP2 exhibit high conductivity and anisotropic transport...

Solar energy plays a vital role in reducing energy deficits by providing a renewable and sustainable power source, and it significantly reduces contributions to climate change compared to fossil fuels. A deeper understanding of the concepts involved in the study of solar energy is crucial for the...

This dissertation is devoted to the investigation of the optical properties of two topological insulators, Bismuth Selenide (Bi2Se3) and Antimony Telluride (Sb2Te3), by optical spectroscopy reflection measurements in a wide frequency range (500 – 40000 cm−1 ) and temperature (13 to 300 K) ....

Well-illuminated streets play a vital role in enhancing the security and well-being of residents in cities and towns. Investing in solar street lighting can reduce costs spent on grid electricity bills. It can also enhance safety and security at the same time uplift the economy of, women and men...

The increase in availability of diagnostic tools and increase in awareness of cancer disease, has enabled the diagnosis of new cancer cases that were not previouslycaptured in Zambia. Today, the Cancer Diseases Hospital (CDH) treats over 3,200 cancer patients annually, a number significantly...

The power utility company in Zambia, the Zambia Electricity Supply Corporation (ZESCO) introduced load-shedding in urban and rural areas in 2015 when the country experienced severe drought and caused low water levels in our hydropower stations for power generation and distribution. To mitigate...

Climate change has greatly affected Zambia’s hydropower production. This has contributed to reduced amounts of electricity being injected into the utility grid. Zambia has therefore embarked on igniting different solar energy initiatives. However, no critical study has been done to document the...

The Solar mini-grid initiatives aim to provide access to electricity to rural and remote areas which are currently not connected to the national grid. However, the implementation of solar mini-grids in Zambia presents challenges and therefore understanding the success factors and challenges of...

Polymer Solar Cells (PSCs) have attracted great attention due to the advantages of their light weight, flexibility and low cost. The typical device architecture of polymer based solar cell consists Indium Tin Oxide (ITO) on glass as the transparent conducting electrode,Poly (3,...
