In the paper, the optical properties of GaN wedge-shaped quantum dot (WSQD) under influence both pressure and electron-phonon (e-p) interaction have been investigated. To this end, the energy difference and dipole matrix elements are evaluated by considering the effects of e-p and pressure. Then, the refractive index changes (RICs) and absorption coefficients (ACs) are evaluated. It is deduced that the energy difference and dipole matrix elements reduce by considering the e-p and pressure effects. It is resulted that the pressure enhances the e-p effect on the energy difference. The ACs and RICs move to lower energies by considering the ep and pressure effects. The RICs and ACs are raised in the presence of e-p effect whereas they are reduced with considering the pressure. With considering the e-p and pressure effects on total ACs, it is seen that the peak of AC splits into two peaks.

“…These devices play important roles in the fields of medicine, military, telecommunication, and many others [13][14][15][16][17]. The semiconductor quantum wires, one of the low-dimensional structures that possess many special properties, have drawn the attention of scientists [18][19][20][21][22]. These structures could be applied to create high-speed lasers [23,24], quantum electron waveguides [25], resonant tunneling field-effect transistors [26,27], or telecommunication networks [28].…”

This study looks at the three-level optical Stark effect of excitons in GaAs cylindrical quantum wires, utilizing the renormalized wave function theory. By applying the three-level model consisting of the first two electron levels connected via a powerful pump laser and the first hole level, we observe the appearance of the excitonic optical Stark effect through the appearance of two separated peaks in the exciton absorption spectra. In addition, the strong impact of the pump laser detuning and the wire radius on the optical Stark effect are also put under thorough examination. Finally, a brief guidance for experimental verification is also suggested.

a b s t r a c tIn this paper, we have studied the effect of electron-phonon (e-p) interaction on the second harmonic generation (SHG) and third harmonic generation (THG) of modified Gaussian quantum dots within the framework of the compact density matrix approach and iterative method. We have obtained the energy eigenvalues and their corresponding eigenfunctions of the system without ep interaction and under the influence of electron-LO phonon, electron-SO phonon, and electron-LO + SO phonon interaction. It is found that the effect of the electron-phonon interaction has a great influence on the second and third harmonic generation of the system. The effect of electron-SO phonon on the SHG and THG is greater than the electron-LO phonon. The electron-LO + SO-phonon interaction has the largest contribution to the SHG and THG.
