| Research Abstract |
It is vital to clarify the charge transfer mechanism in organic semiconductors. In this study, we explored the electronic structures of holes injected at the interface between organic semiconductor and insulator by charge modulation spectroscopy (CMS). We developed a method to apply CMS to opaque devices that cannot be probed by the conventional transmittance configuration. In addition, we found that the CM spectra of holes in DNTT thin film transistors depend on the alkyl chain length introduced both ends of the molecule. A theoretical analysis of the spectra allowed us to deduce a correlation between charge transfer probability and molecular configurations.
