In recent years it has become technologically possible to engineer devices in which the electrons and holes are spatially seperated in two different layers. The thus increased life-time combined with the bosonic nature of excitons opens up the promise of exciton Bose-Einstein condensation. Whereas most research is focussed on exciton condensation in coupled semiconductor quantum wells or graphene, little attention is devoted to the class of doped Mott insulators. We investigate the properties of excitons in coupled electron and hole doped Mott insulator layers. In the undoped Mott insulator insulator see picture each lattice site is occupied by a single electron and their spin is antiferromagnetically ordered.
Doping — ie the addition or removal of electrons by chemical substitution or applying a gate voltage — leads to the occurence of either double occupied or vacant sites. George A. Poster [pdf-file].
