Description
Summary:► The effects of the confinement on the susceptibility are investigated. ► Calculations are performed in GaAs, Si, and Ge quantum wells. ► It is observed that the χz part contribution to the χT is negligible for γ100Å, and the impurity is located at center. Moreover, a two parameter trial wave function model gives higher values of diamagnetic susceptibility, except for χz (GaAs).
