Final Report Abstract

 The MEMORY project involves an interdisciplinary collaboration between theoreticians and experimentalists from 4 countries.  Main idea: Creating oriented arrays of conductive nanowires as components in a memory device fabricated with non-lithographic means.  Methodology: Assembling nanoparticles with block copolymers in thin films under the application of an electric field.  Progress to date: Developing fundamental understanding of interfacing functional nanoparticles and block copolymers under electric fields.  Main challenges: extremely long delays (from months to over a year) in the transfer of funding throughout the entire duration of the project caused us to re-formulate our research goals.  Main outcomes: Development of new experimental and theoretical knowledge; formation of new collaborative ties, which persist after the termination of this project; training young scientists in all groups.
