The wave packet study of exciton dynamics in the ZnSe_ZnTe Quantum well

摘要

In this paper we perform a detailed study of the formation and the dynamics of the exciton on the ZnSe/ZnTe quantum well taking into ac- count two-particle nature of the process. The electron-hole interaction is included in the model through the electrostatic potential. Which results in a nonlinear coupling of the electron and hole equations of motion. The cou- pled time-dependent Schrodinger equation describing the electron and hole dynamics is integrated numerically. The detailed dynamics of the excitonic electron-hole pair in the quantum well is presented for different uniform electric field applied across the structure.
