The ground state total and correlation energies of a negative ion-electron and electron-electron systems in a parabolic QD with standard dispersion law are theoretically investigated in an external magnetic field by a variational approach. Both cases of finite and infinite potential barrier on the spherical surface of the QD are considered. The negative ion-electron system energies in a A3B5 semiconductor QD with nonparabolic (Kane's) dispersion law is also investigated. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
