Observations of indirect exciton trapping in one- and two-dimensional
magnetic lattices    [PDF]

Ahmed M. Abdelrahman, Byoung S. Ham

A simple method to create and control magnetic potentials onto coupled
quantum wells is demonstrated for indirect-exciton magnetic confinement.
Localized inhomogeneous magnetic potentials with periodically distributed local
minima and maxima, known as magnetic lattices, are projected into the plane of
the coupled quantum wells and used for the spatially distributed
two-dimensional indirect-exciton trapping, in which case localized
indirect-excitons are observed. The indirect-exciton trapping mechanism is
examined by controlling external magnetic field bias resulting in a shift of
the localized excitonic lattice.
