摘要：
We study the interband absorption spectrum of a charged magnetoexciton in two-dimensional (2D) parabolic quantum dots containing N(0 less than or equal to N less than or equal to 12) electrons by using an unrestricted Hartree-Fock method. The calculated results show red shifts of interband transition energies, reduction of diagonal transition intensities and suppression of diamagnetic shift of transition energies, by the charging effect of a quantum dot. The mechanisms of these charging effects are clarified.
