Final Report Abstract

In this project, we could approve the proposed concept and demonstrate increased memory retention by tuning the molecular design of the SAM molecules. The outcome in the general understanding of SAM formation, characteristics and morphology is even more important and reflects also the growing field of smart self-assembled molecules in all kind of applications as universal engineering tool. The pressure to search for alternative analytics turned out as “lucky chance” because it extended the scope to theory and implemented X-ray techniques as powerful tool. The future of the topic will hopefully to be continued and extended by the applied SPP “FlexMem”. However, self-assembled materials in general will perform in different applications and will be in strong focus.
