ABSTRACT
Localized electronic states in coupled superlattices are investigated. A special case of two identical semi-infinite superlattices coupled by a barrier spacer in their symmetry point (i.e., in the barrier/ well center) is considered. Conditions for the existence of interface localized states, compatible with the system symmetry, are found. The theory is applied to numerical calculations of the interface localized states in Al[sub x]Ga[sub 1-x]As coupled superlattices.
