چکیده انگلیسی
The magneto-optical absorption coefficients (MOAC) and the full-width at half-maximum (FWHM) in a quasi-zero-dimensional quantum dot (QD) via two-photon process are theoretically studied in which the electron-phonon (e-p) interaction is involved. It is found that the best range of the magnetic field to observe the MOAC is from Bâ¯=â¯3.49â¯T to Bâ¯=â¯15.77â¯T. As the magnetic field enhances, the peaks intensities firstly enhance, reach the maximum value at Bâ¯=â¯5.38â¯T, and then start reducing if the magnetic field continues increases further, while the peaks positions give a blue-shift. Besides, the magneto-optical absorption properties are found to be significantly affected not only by the quantum dot parameter but also by the temperature. The FWHM rises nonlinearly with the enhance of the magnetic field, the confinement frequency, and the temperature. The two-photon process makes an appreciable amount of the total absorption process.
