Özet

A theoretical investigation of the optical and electronic properties produced by a Manning-type double quantum well under the impact of varied electron effective mass and intense laser field has been implemented within the effective mass approximation (EMA). By selecting an appropriate wavefunction, we have computed the eigenvalues and their eigenfunctions using a diagonalization method. After that, the optical absorption coefficients (OACs) were calculated using a two-level approximation. The obtained findings reveal that the optical and electronic properties of the structure under consideration can be regulated to achieve appropriate response to specific needed studies or aims by modifying the structural parameters and sizes such as the width and depth of each well, the coupling distance between them, and the intensity of the applied intense laser field. The obtained results show the flexibility of the Manning potential which can be altered by adjusting its structural parameters and varying an applied intense laser field such flexibility can be applied to arrange the energy spectrum and optical absorption shifts in novel optoelectronic devices.
