Research Abstract |
Hetero-interfaces between an organic semiconducting material and an electrode metal, gate insulator, or another organic semiconductor are one of the most crucial factors dominating the performance of the practical organic electronic devices. In the present study, the electronic structures of such organic hetero-interfaces were elucidated on well-ordered interfaces fabricated onto the organic single crystal surfaces by means of angle-resolved photoelectron spectroscopy. On the rubrene single crystals covered with an overlayer of a normal alkane molecule as a model interface of the channel region a high-mobility organic field effect transistor, un-modified valence band dispersion width (i.e. band effective mass of conducting holes) was revealed. Hetero-interfaces of organic semiconductors with other organic materials or electronically quantized metal nano-structures were also systematically investigated.
