| Research Abstract |
In this study, measurement techniques of nonradiative process in organic semiconductor thin film devices were developed by using microphone technique and transducer technique. In microphone technique, measurement cell was made up of silicon rubber and a substrate of devices, and it is demonstrated that the photo-acoustic signal and the photocurrent signal under applying voltage were measured at the same time. As a result of that, the both characteristics show good agreement under applying voltage and red illumination light,
On the other hand, in a transducer technique, output signal was increasing with increasing the film thickness.
