| Research Abstract |
Electric field control of materials properties is one of the longstanding issues in solid-state science. With this technique one can observe disorder-free phenomena upon carrier doping and find novel electronic states that are impossible to generate in a chemical way. In this project, we are going to employ an electrochemical concept to control materials properties with an electric field. The purpose of this project is to explore this new window of extreme charge doping that has never been reached so far by field effect, to search for and control novel states of matter in well chosen materials. We have achieved : (1) observation of electric field induced metal-to-insulator transition in variety of materials such as intrinsic semiconductors: VO2, and SrTiO3, (2) observation of electric field control over magnetic ordering and phase transitions in Co, (3) development of new light-emitting diodes with EDL gating technique.
