THREE-ELECTRON SYSTEMS IN SPHERICAL PARABOLIC GaAs QUANTUM DOTS

By making use of the method of few-body physics,the energy spectra of low-lying states of a three-electron spherical dot have been calculated. The quantum-size effects on the energy spectra of three electrons are shown.The res ults show that the orders of energy levels do not change when quantum dot diamet ers change. As a result, the energies of the states of L=3k (k=1,2,…) fulfilling \pi (-1)^L=1 are lower than those of their adjacent states.
