Abstract

Spatially nonhomogeneously spin polarized nuclei are proposed
as a new mechanism to monitor electron states in a
nanostructure, or as a means to create and, if necessary,
reshape such nanostructures in the course of the experiment. We
found that a polarization of nuclear spins may lift the spin
polarization of the electron states in a nanostructure and, if
sufficiently strong, leads to a polarization of the electron
spins. Polarized nuclear spins may form an energy landscape
capable of binding electrons with energy up to several meV and
the localization radius > 100 Angstrom. (C) 2002 Elsevier
