Magneto-optic properties of InAsN and InN quantum dots doped with Co or Ni atoms

Abstract

The electron energy level structure and charge and spin distributions of small InN and InAsN quantum dots (QDs) doped with Co or Ni atoms were studied using first-principle quantum many body field theoretical methods. In agreement with existing experimental findings, the obtained results show that nitrogen atoms in the studied small QDs accumulate the electron charge. It was also found that nickel atoms orchestrate electron charge redistribution necessary to stabilize such small systems.
