摘要
Using a variational approach, the binding energy of hydrogen impurities in (i) spherical quantum dots with parabolic confinements in an electric field and (ii) disc-like quantum dots with parabolic lateral confinements in a parallel electric field art: calculated. Both the confinement and the electric field effects on the binding energy are investigated in detail.
