摘要
The Hamiltonian of a negatively charged exciton X- (trion) in a GaAs quantum dot with parabolic confinement has been diagonalized to obtain the low-lying eigenenergy values as a function of the dot size and the electron to hole effective mass ratio. We find that there are level reorderings as a, the mass ratio, varies continuously from 0.1 to 1.0. (C) 1998 Elsevier Science Ltd. All rights reserved.
