The Wave Packet Study of Exciton Dynamics in the ZnSe-ZnTe Quantum Well

In this paper we perform a detailed study of the formation and the dynamics of the exciton in the ZnSe/ZnTe quantum well taking into account 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 coupled 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.
