| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It takes nanoseconds to milliseconds for an electronic device to arrive at one’s steady state from the beginning of the voltage application, so we usually do not perceive this time. However, observation of the transient state during the device rising time is crucial in the frontline of the novel device development because they have to know where is the bottleneck of the present device structure. We have proposed our extended time domain reflectometry (ExTDR) to observe the transient impedance and reveal the carrier dynamics of the electronic devices. Time-domain reflectometry (TDR) was an instantaneous impedance detection method that was used in disconnection detection of long-distance communication cable or soil surveys. In this work, we extended conventional TDR and adopted it to detect the transient impedance of thin-film devices. We have indicated the carrier dynamics in OTFT and OLED. Moreover, we recently developed light synchronized TDR to observe the initial photo-carrier generation process in OPV. We introduce the principle of ExTDR and Light synchronized TDR measurement and examples of carrier dynamics of the OTFT, OLED, and OPV from 10 ns to 10 ms time region. | |
