A detailed investigation of the optical properties of a spherical quantum dot (QD) containing
one and two electrons has been performed for cases with and without a hydrogenic impurity …

In quantum dot structures, photoionization has been considered as an optical transition from
the impurity ground state to the conduction subbands. Using a variational approach, we …

In this paper, within the effective mass approximation and by using the finite element
method, we have studied the photoionization cross section (PCS) and the binding energy of …

We have studied the behavior of the binding energy and photoionization cross-section of a
donor-impurity in cylindrical-shape GaAs-Ga 0.7 Al 0.3 As quantum dots, under the effects of …

Within the effective-mass approximation, we have investigated the influence of a strong
magnetic field on the ground state binding energy and the photon energy dependence of the …

Using the variational method and the effective mass and parabolic band approximations, the
behaviour of the binding energy and photo-ionization cross section of a hydrogenic-like …

In this study, we have investigated the photoionization cross section of an on-center
hydrogenic impurity in a multi-layered spherical quantum dot. The electronic energy levels …

This study reports a theoretical investigation on the electronic spectrum and the
photoionization cross section of a singly ionized double donor complex D 2+ confined in a …

We consider the effects of hydrostatic pressure and temperature on the binding energy and
photoionization cross section of hydrogen-like impurity in Pöschl–Teller quantum well. The …

The laser-field dependence of the impurity binding energy and donor-related
photoionization cross-section in graded quantum-well wire under an external static electric …
