Abstract

AbstractFew‐particle clusters of spatially separated electrons and holes in vertically coupled two‐dimensional quantum dots are analyzed. As a function of interdot distance d, the inlayer interaction between electrons (and holes) changes from Coulomb repulsion at large d to dipole repulsion of e‐h pairs at small d. The change of the structural properties (cluster shell configuration and symmetry) and energy with variation of d is investigated. (© 2003 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
