Bound spin-excitons in two-dimensional electron gas
A theory of the spin exciton capture by a magnetic impurity in a 2D electron gas is developed. We consider a resonance model for the electron scattering by a transition metal impurity and calculate the binding potential for spin excitons. This potential is spin selective and is capab...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | A theory
of the spin exciton capture by a magnetic impurity in a 2D electron gas is developed. We
consider a resonance model for the electron scattering by a transition metal impurity and
calculate the binding potential for spin excitons. This potential is spin selective and is
capable of binding a spin exciton with zero angular momentum. In order to trap an exciton
with a nonzero angular momentum m, the potential must exceed a certain threshold value,
depending on m. |
