  • Development of small AC voltage superimposed displacement current measurement for light-emitting electrochemical cell, Tanaka Yuya, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B), Grant-in-Aid for Young Scientists (B), Chiba University, Apr. 2017, Mar. 2020, To deeply understand operation mechanism of light-emitting electrochemical cells (LECs) and put them into practical use, evaluation of dynamics of carriers such as charges and ions is highly required. In this study, by combining displacement current measurement (DCM), which can observe carrier dynamics, and impedance spectroscopy (IS), which enables quantitative analysis of impedance (Z), we developed small AC voltage superimposed DCM (AC-DCM). The AC-DCM successfully separated Z in forward and reverse scans, and we found that Z in the forward scan is larger. These results suggest that AC-DCM is a powerful tool to observe the dynamics of carriers in LEC., 17K17640, url

  • Direct observation of gap states in organic semiconductors and elucidation of device properties, ishii hisao, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Chiba University, Apr. 2016, Mar. 2020, Coinvestigator, The level existing in the HOMO-LUMO gap of organic semiconductors is an important factor that holds the key to the performance of various organic electronic devices, but it cannot be observed directly, and has been indirectly evaluated from electric properties on the basis of models. In this study, we improved the high-sensitivity photoelectron spectroscopy; we have succeeded in observing weak gap levels at the detection level of 1/100 million. We also succeeded in roughly evaluating the unoccupied gap level in combination with the results of high-sensitivity absorption spectroscopy. In addition, the electronic structures of thin films and interfaces related to solar cells, triboelectrification, organic EL, proteins, etc. were measured with high sensitivity, and the relationship between device characteristics and electronic structure was clarified., 16H04222, kaken
