Outline of Final Research Achievements |
The purpose of this work is to develop an electrochemical reactor which enables us to dope hetero anionic species to the target material. As proof of concept, fluorine doping reactor was assembled by using solid fluoride-ion conductor, and fluoride-ion was successfully doped into the perovskite oxides. However, chlorine doping was not succeeded probably due to huge mismatch of ionic-size between oxide-ion and chloride-ion. Findings of this work are important guidelines for further development of new material exploration techniques.
