Topic: Development of iontronics

Speaker:  Shimpei ONO1

1Central Research Institute of Electric Power Industry (CRIEPI), Materials Science Research Laboratory, 2-6-1 Nagasaka, Yokosuka, Kanagawa, Japan

Time: 15:00-16:30, (Tuesday) June 26th, 2018

Venue: Room 468,LeeHsun Building, IMR CAS

Electric field control of charge carrier density has long been a key technology to tune the physical properties of condensed matter, exploring the modern semiconductor industry. One of the big challenges is to increase the maximum attainable carrier density, however it is limited by the quality of gate dielectrics. In this talk, I’m going to show the new technique to modulate carrier density making use of ionic liquid electrolytes. With electrolyte gating, we can modulate up to 1015/cm2 of carrier density at the interface which is 2 orders of magnitude larger than conventional gate dielectrics and demonstrate that we can indeed control metal-to-insulator and ferromagnetic-paramagnetic transition by electric-field effect doping. I also will show our recent progress using ionic liquid electrolytes.
