Coulomb repulsive correlation in A~3B~5 semiconductor quantum dots in the presence of a magnetic field

摘要

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 A~3B~5semiconductor QD with nonpa-rabolic (Kane's) dispersion law is also investigated.
