Abstract
The formation of spatially indirect excitons in superlattices with nar row minibands is investigated experimentally. The interwell exciton is similar to the first Wannier-Stark localized exciton of an electrical ly biased superlattice. However, in the present case the localization is mediated by the Coulomb interaction of the electron and the hole wi thout external fields. (C) 1997 Academic Press Limited.
