Outline of Final Research Achievements

We paid my attention what kind of electronic level bending in organic devices under bias condition, and performed three-dimensional mapping of the electronic states of the devices by electron spectroscopy and electron emission microscope. Especially understanding the electronic states near the Fermi level, we were able to give a guidance to control a charge injection barrier and a charge transport property of a novel organic device.
