Spin Relaxation in Mn doped CdTe/ZnTe QDs

Manifested luminescence and magnetic responses of stoichiometry dependent Cd1− xMnxSe quantum dots

“…This is because, these QDs exhibit special properties, like localization of magnetic ions that result in free electron and hole carriers [1,2], size-dependent sp-d exchange interaction [3,4] along with introduction of new energy levels within the forbidden gap. The strong sp-d exchange interaction may result in enhanced spin relaxation [5], giant Zeeman splitting of the electron and hole states when subjected to a magnetic field [6], along with the formation of excitonic magnetic polarons [3,7]. These interesting characteristics occurring in ms-NCs ensure their potential applicability in various fields including spintronics [8], tunable lasers [9], solar cells [10], magneto-optic elements [11], quantum computing etc.…”
