| 中文摘要 | we have studied the exciton states in vertically stacked self-assembled quantum disks within the effective mass approximation. the energy spectrum of the electron and hole is calculated using the transfer matrix formalism in the adiabatic approximation. the coulomb interaction between the electron and the hole is treated accurately by the direct diagonalization of the hamiltonian matrix. the effect of the vertical alignment of the disks on the ground energy of heavy- and light-hole exciton is presented and discussed. the binding energy is discussed in terms of the probability of the ground wave function. the ground energy of heavy- and light-hole excitons as a function of the magnetic field is presented and the effect of the disk size (the radius of disks) on the exciton energy is discussed. |
