The purpose of this research is to reveal the occurring mechanism for spin properties of organic semiconductor devices by developing a new analytical technique combining magnetic resonance with a combination technique of semiconductor device operation and a spectroscopic technique. We indeed succeeded in developing a system enabling to observe spectroscopic signals in an ESR apparatus. In order to identify the presence of the ESR response in the signals from device modulation measurements, we attempted several experiments. However, we were not able to observe such signals, unfortunately. We concluded that the reason would be because the amount of carriers contributable to the signals was smaller than expected.

本研究的目的是通过开发一种新的分析技术，结合磁共振与半导体器件操作和光谱技术的组合技术，揭示有机半导体器件的自旋性质的发生机制。我们确实成功地开发了一种能够在ESR装置中观察光谱信号的系统。为了识别来自器件调制测量的信号中ESR响应的存在，我们尝试了几个实验。然而，不幸的是，我们未能观察到这些信号。我们得出的结论是，原因可能是因为有助于信号的载体的数量比预期的要少。
