The amazing experimental progress in fabrication processes of layered structures has led to a fascinating new research field: artificial structures of complex materials with strongly correlated electron systems. There is a bright perspective for intriguing new physics with potential for applications. This new field is still in its infancy and many fundamental as well as more applied questions have to be investigated. The book on hand tries to find answers to some of them.
