We investigated the effect of the electronic confinement potential on the electron–LO-phonon (el–LO-ph) interaction energy in a quantum well by using the variational method. In this work, the el–LO-ph interaction energy in the infinite (I) and finite (F) square potential quantum wells (SPQW) is calculated as a function of the well-width for all four different confined-optical-phonon (COP) models. The result shows that the el-LO-ph interaction energy in a quantum well is affected strongly by the electronic confinement potential for all four COP models. Except for the Ridley-Babiker model, the el-LO-ph interaction energy in the ISPQW is always larger than that in the FSPQW for both the lowest phonon modes of different COP models in the narrow well case. The Fuchs-Kliewer and the Knipp-Reineck models have a good agreement in the description of the el-LO-ph interaction for the ISPQW, while that is the Fuchs-Kliewer and the Huang-Zhu models for the FSPQW. Among the above four models, the Fuchs-Kliewer model is the most effective.

“…[28] Cyclotron resonance absorption and the effect of phonon confinement on the cyclotron resonance have been investigated using the projection operator method. [29] The absorption power was calculated for the Ridley, Fuchs-Kliewer, and Huang-Zhu confined phonon models. These studies are important in assessing the results of temperature, photon energy, well width, and magnetic field strength on the absorption or emission interactions of the encompassed phonon for GaAs quantum wells, and they clearly demonstrated the results of these effects.…”

In this study, for the first time, the velocity‐dependent potential (VDP) effects on the total refractive index changes (TRICs) and the total absorption coefficients (TACs) of the parabolic quantum dot with spherical confinement, generated by GaAs/GaAlAs heterostructure, are comprehensively investigated. In order to obtain the subband energy spectra and the electronic wave function of the quantum dot system, the wave equation is numerically solved due to the VDP's complexity by using Runge‐Kutta‐Fehlberg method within the effective mass approximation. The nonlinear optical specifications of the quantum dot with velocity‐dependent potential (QDVDP) are analyzed using the compact density matrix formalism within the framework of the iterative method. To investigate the optical specifications of QDVDP, the isotropic form factor of VDP is taken into consideration as the harmonic oscillator type, F(r) = γρ0r2 (being γ and ρ0 are constants). Optical analysis is also executed for parabolic encompassing under the influence of VDP, as well as VDP, analyzing for TRICs and TACs of QDVDP, for which the result is quite a change compared to cases without VDP due to the symmetry‐breaking repercussion on system confinement of VDP. The main motivation of the present study is to clearly distinguish VDP effects on optical properties of the quantum dot, carrying out an analysis on optimal range and alternative parameter for optical properties.
