In this work, for the first time, the total refractive index (TRICs) and total absorption coefficients (TACs) of In\(_{x}\)Ga\(_{1-x}\)As/GaAs Mathieu quantum dot (MQD) with hydrogenic impurity under the influence of the external electric field and laser field are probed. Within the framework of the Ehlotzky approximation, considering the Kramers–H...

The on-center shallow-donor impurity binding energy in lattice matched InP/In0.53Ga0.47As square quantum well structure have been theoretically investigated using effective mass and variational techniques.

In this study, the electronic energy levels of GaAs/ InxGa1-xAs/GaAs single square quantum well (SQW) have been analytically calculated. The numerical results have clearly illustrated the electronic energy levels dependency to the SQW structure parameters. Such as, In concentration, the barrier height and the width of the well

Within the framework of effective-mass approximation, the binding energy of a hydrogenic donor impurity in zinc-blende (ZB) InxGa1−xN/GaN cylindrical quantum well wires (CQWWs) is investigated using variational procedures. Numerical results show that the ground-state donor binding energy Eb increases when the hydrostatic pressure increases for any...

We have presented the behavior of a shallow donor impurity with binding energy in cylindrical-shaped GaAs/Ga0.7Al0.3As quantum well wires under high hydrostatic pressure values. Our results are obtained in the effective mass approximation using the variational procedures. In our calculations, we have not considered the pressure related Γ−X crossove...
