| Outline of Final Research Achievements |
In order to understand and improve electronic devices using organic semiconductors, it is indispensable to answer basic questions about "carrier" to carry electricity; "How is carrier injected to organics?", "How is carrier extracted from organics?" etc. The mechanism of carrier injection and extraction has been so far discussed on the basis of the energy position of frontier molecular orbital of organic materials. In this study, the electronic structures of films and interfaces of several organic materials were investigated by our unique technique, high sensitivity photoelectron spectroscopy, and the mechanism was discussed on the basis of the observed density of states as well as frontier orbital positions.
