摘要
An efficient numerical method for exciton states in thin quantum boxes is developed, which is more promising than the standard configuration-interaction (CI) approach. The exciton wave function is expanded in terms of coordinate eigenstates on each grid point. The discrete variable representation (DVR) is used as the basis set for the wave function. The DVR is a coordinate eigenfunction localized on each grid point associated with the Gaussian quadrature rule. The energy, eigenfunction, and electron-hole separation of the exciton are obtained for various widths of the quantum box.
