Abstract

In this work, the energy levels and wave functions of the pyramidal quantum dot (PQD) are numerically calculated using the finite element method. Then, the refractive index changes (RICs) and absorption coefficients (ACs) are determined. To this goal, we have used the compact-density matrix method. Numerical results have been presented for the GaAs/Al x Ga 1 − x As pyramid quantum dot. It is found that the change of structural parameters like quantum dot sizes has an important influence on energy levels, wave functions, and optical properties of PQD. With increasing the height of PQD, the Acs, and RICs increase and shift toward higher energies. [ABSTRACT FROM AUTHOR]
