PECASE: Nanostructure Hybrid Organic/Inorganic Materials for Active Opto-Electronic Devices

摘要

The scope of this proposal is nanoscale integration of organic and inorganic materials into hybrid optoelectronic structures to create active devices that combine the diversity of organic materials with the high performance electronic and optical properties of inorganic nanocrystals. The proposal addresses three areas of nanoscale intergration and active device development: (1) the directed structuring of materials at the nanoscale through pattening and material growth methods, (2) the development of model systems as test beds to understand electrical and optical processes in hybrid organic/inorganic materials, and (3) applying the physical principles learned to the development of high-performance active nanostructured devices. The following preliminary applications are proposed as examples of technologies that can be substantially enhanced by our methods: (1) hybrid organic/inorganic light emitting devices (LEDs) based on engineered organic/nanocrystal junctions, (2) hybrid organic/inorganic efficient photodectors with tunability from the UV to the IR, and (3) nanopatterning at 2 to 10 nm scale using periodic arrays of ordered nanocrystals.'.
