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.

有机场效应晶体管（OFET）作为新型电子器件备受关注。基于载流子注入时 OFET 中半导体/电介质界面有机分子的结构变化来揭示载流子注入和传输机制非常重要。在这项研究中，通过电荷调制光谱的方法获得了红荧烯单晶器件中载流子的吸收光谱，该方法选择性地给出了由于施加栅极电压而引起的吸光度差异。获得的光谱与先前研究中获得的光谱不同。
