Nitrogen Doping of Hexagonal and Cubic Ge2Sb2Te5 Nanocrystals: An Ab Initio Study
(World Scientific Publishing Company, 2018)
The effect of nitrogen doping on the structural, electronic and optical properties of hexagonal and cubic Ge2Sb2Te5 (GST) has been investigated from first principles. The nitrogen content was set to 10 at.% and 25 at.%, ...
Effect of Reverse Bias on Dye-Sensitized Technology: Lessons for Application in PV-Integrated Textile Fabric Designs Useable in Wajir, Vihiga, Kitui and Kajiado Counties in Kenya
(Journal of Technology Innovations in Renewable Energy, 2018)
This paper reports on the effect of reverse bias (RB) on dye-sensitized solar cells (DSSCs) that were investigated outdoor in Wajir (1o4450 North, 40o 4 8 East), Vihiga (35o0 East, 0o15 North), Kitui (3o 0 South, 37o 50 ...
Determining SU (N) symmetry group generators
(Research gate, 2018)
SU(N) symmetry groups are useful in formulating gauge theories of elementary particle interactions
in quantum field theory. Gauge bosons and particle states are associated with the symmetry group
generators. The accuracy ...
SU (N) generator spectrum
(Research gate, 2018)
This paper provides an accurate mathematical method for determining SU(N) symmetry group generators in a general N-dimensional quantum state space. We identify the generators as well-defined quantum
state transition and ...
Compositional and Thickness Effects on the Optical Properties of Zinc–Doped Selenium–Antimony Thin Films
(Tanzania Journal of Science, 2018)
Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising semiconductor for phase change memory devices due to its thermal stability and low power consumption. The study investigated the effect of ...

A note on momentum and energy conservation in dynamics under arbitrary forces in classical Newtonian and relativistic mechanics
(Research gate, 2018)
In teaching mechanics course to first year undergraduate students, I have come across a simple, but very important, gap in the formulation of the principle of conservation of momentum and energy in the dynamics of a body ...
[HTML] from rsc.org Effect of thermal treatment on ZnO: Tb 3+ nano-crystalline thin films and application for spectral conversion in inverted organic solar cells
(Royal Society of Chemistry, 2018)
Down conversion has been applied to minimize thermalization losses in photovoltaic devices. In this study,
terbium-doped ZnO (ZnO:Tb3+) thin films were deposited on ITO-coated glass, quartz and silicon
substrates using ...
Devolved ethnicity in the Kenya: Social, economic and political perspective
(Sciendo, 2018)
act
This paper examines the ethnicity as an issue prevailing upon the Kenyan society and its implication on
the social, economic and political dimensions in Kenya. Devolved ethnicity has been seen to be on the arise
since ...
Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
(AJOL, 2018)
Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising
semiconductor for phase change memory devices due to its thermal stability and low power
consumption. The study investigated the effect ...
