Electron-LO-phonon intrasubband scattering rates in a hollow cylinder under the influence of a uniform axial applied magnetic field
(Springer Science+Business Media, LLC, part of Springer Nature, https://www.springer.com/journal/11082, 2021-11-06)
Scattering rates arising from the interactions of electrons with bulk longitudinal optical (LO) phonon modes in a hollow cylinder are calculated as functions of the inner radius and the uniform axial applied magnetic field. ...
Seismicity Study of Botswana from 1966 to 2012
(Scientific Research Publishing Inc., https://www.scirp.org/journal/ijg/, 2018-12-29)
The history of Botswana’s major seismic events has been initiated by two earthquakes that occurred on the 11th of September and 11th of October 1952 with ML Richter magnitudes of 6.1 and 6.7, respectively, in the Okavango ...
Electrophilicity of oxalic acid monomer is enhanced in the dimer by intermolecular proton transfer
(Royal Society of Chemistry, https://pubs.rsc.org/en/journals/journalissues/cp#!recentarticles&adv, 2017)
We have analyzed the effect of excess electron attachment on the network of hydrogen bonds in the oxalic acid dimer (OA)2. The most stable anionic structures may be viewed as complexes of a neutral hydrogenated moiety HOA˙ ...
Natural pigments as photosensitizers for dye-sensitized solar cells with TiO2 thin films
(Gazi University, https://www.ijrer.org/ijrer/index.php/ijrer, 2015)
Dye-sensitized solar cells (DSSCs) were fabricated using four natural dyes extracted from the leaves of lemon (Citrus limon) and morula (Sclerocarya birrea) and flowers of bougainvillea (Bougainvillea glabra). Optical ...
Optical transition rates in a cylindrical quantum wire with an inverse parabolic potential
(Opast Group LLC, https://www.opastpublishers.com/journal/advances-in-theoretical-computational-physics, 2019-05-25)
Electron transition rates due to interaction with circularly polarized light incident along the axis of a free-standing solid cylindrical nanowire are evaluated in the dipole approximation. In this case, the allowed optical ...
Wildfires in Botswana and their frequency of occurrence
(Scientific Research Publishing Inc., https://www.scirp.org/journal/journalarticles.aspx?journalid=492, 2021-09-13)
Fires play an essential part in the maintenance of the environment, but amplified fire activity often leads to adverse effects in the environment such as destruction of property and loss of life. Botswana has experienced ...
The effects of cup-like and hill-like parabolic confining potentials on photoionization cross section of a donor in a spherical quantum dot
(EDP Sciences, Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature, https://www.springer.com/journal/10051, 2016-08-08)
A theoretical investigation of the effects of hill-like and cup-like parabolic confining electric potentials on photoionization cross section (PCS) in a spherical quantum dot is presented. The hill-like and the cup-like ...
Diamagnetic susceptibility and optical properties of a spherical quantum dot: effects of the parabolic and the shifted parabolic potentials
(Springer Science+Business Media, LLC, part of Springer Nature, https://www.springer.com/journal/11082, 2019-06-22)
Centred charge donor related diamagnetic susceptibility and optical properties of a spherical GaAs quantum dot are presented. In particular, effects of intrinsic parabolic and shifted parabolic potentials on these quantities ...
Probing semiconductor quantum well qubits and associated Shannon entropy using semi‑relativistic quantum mechanics
(Springer Nature, https://www.springer.com/, 2023-08-07)
Electron states in GaAs, GaN and AlN quantum wells are studied by solving a semi-relativistic wave equation within the effective mass approximation. The quantum states are in turn used to probe the properties of two-level ...
Effect of an inverse parabolic confining electric potential on third harmonic generation in cylindrical quantum wires
(EnPress Publisher, LLC, https://systems.enpress-publisher.com, 2019)
A theoretical investigation of the effect of an inverse parabolic potential on third harmonic generation in cylindrical quantum wires is presented. The wave functions are obtained as solutions to Schrödinger equation solved ...
