Nanoscale electronic devices via templating supramolecular polyelectrolytes (NEDSPE)

• Applicant: Professor Dr. Manfred Stamm
• Subject Area: Preparatory and Physical Chemistry of Polymers
• Term: from 2003 to 2007
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5414184

The project deals with the development of single molecule templating strategy for the fabrication of nanobjects with dedicated shape, size and properties on the base of synthetic polyelectrolytes (PE). Nanowires will be produced via deposition of metal clusters onto the PE molecules in an extended conformation. Conductive-semiconductive nanocomposites will be fabricated by metallization of block copolymers which consist of PE and electroconductive polymer fragments. We plan to develop multiple templating methodology at the single molecule level to built up complicated structures by sequential deposition of different materials onto the same template. Control of PE molecule conformation, metal deposition, morphology and structure of the obtained nanoobjects will be performed using AFM, TEM and XPS methods of investigations. Positioning and addressing of the nanoobjects will be performed via selective adsorption of PE molecules on patterned substrates. We plan to study electron transport in the developed nanodevices.
