Abstract

Theoretical investigations of spin polaron in a quantum dot in the "spin doping" superlattice systems Cd 1 - X in Mn X in Te/Cd 1 - X out Mn X out Te are presented. We estimated the donor ionization energy by variational technique and the spin polaronic shift using the mean field theory with modified Brillouin function. Our results show that significant enhancement of donor ionization energy and spin polaronic shift occur in a dot when compared to a quantum well, wire and bulk systems.
