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 ...
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 ...
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. ...
(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 ...
(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 ...
