Photoionization cross-section in a GaAs spherical quantum shell: the effect of parabolic confining electric potentials
(Springer Nature, https://www.springer.com/, 2021-06-22)Theoretical study on binding energies due to a centred charged impurity and the associated photoionization cross-section (PCS) in a spherical shell are presented. This was achieved by solving the Schrödinger equation within ... -
Optical properties of GaAs nanowires with an electric potential that varies inversely with the square of the radial distance
(Hindawi, https://www.hindawi.com/, 2019-07-10)A theoretical investigation of optical properties of a cylindrical quantum wire (CQW) is presented. The properties studied were optical absorption coefficient (AC) and change in refractive index (CRI) of the quantum wire. ... -
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 ... -
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 ... -
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 ...
