| Research Abstract |
Organic field effect transistors (OFETs) attract great attention as new-type electronic devices. It is important to reveal the mechanism of carrier injection and transport based on the structural change of the organic molecules at the semiconductor/dielectric interfaces in OFETs upon carrier injection. In this study, absorption spectra from the carriers in rubrene single-crystal devices were obtained by the method of charge modulation spectroscopy, which selectively gives absorbance difference caused by application of the gate voltage. The obtained spectra were different from that obtained in a previous study.
