Quantum dots based on spin properties of semiconductor heterostructures

This is the authors' abstract. We don't add key points for this paper.

The possibility of a type of semiconductor quantum dots obtained by spatially modulating the spin-orbit coupling intensity in III-V heterostructures is discussed. Using the effective-mass model we predict confined one-electron states having peculiar spin properties. Furthermore, from mean-field calculations (local-spin-density and Hartree-Fock) we find that even two electrons could form a bound state in these dots.
