03 Organic Device

Developing the science of the surface/interface of organic nanocrystals and organic thin films that is crucial for the advancement of organic electronic materials and organic semiconductor devices, and for the creation of novel organic superconductors


[Target 1] Control of crystal growth and interface structure: Surface/interface holography and photoelectron holography

Highly controlled preparation of crystalline organic thin films will be effected either by precursor approach or vacuum deposition, in order to investigate the relation between the crystal structure and transistor characteristics and to monitor the crystal-growth process at the atomic scale. Holography will be employed to elucidate the mechanism in which the contact resistance is decreased upon modification of the interface structure. In addition, tailor-made organic materials will be synthesized to be used in collaborative projects with the methodology, theory, and application teams.


Target 2Chemical Doping: Doped-atom holography

Arrangement of metal atoms in metal-doped hydrocarbon superconductors and multi-layer 2D materials will be precisely determined by 3D-imaging techniques, and the relationship of superconductive performance with metal-atom arrangement will be investigated.


Target 3Property control by EDL: Surface/interface holography

Interface structure within electric double layers (EDLs) will be investigated at the atomic scale in order to establish the design principles to achieve electric-field-induced phase transition phenomena (e.g., electric-field-induced superconductivity) in EDLs.
