<研究ノート>光誘起電気二重層を用いた有機モット絶縁体における光誘起超伝導

Abstract

Band-filling control of strongly correlated electron systems has been a persistent challenge over the past three decades in condensed matter science. Especially, recent efforts have been focused on electrostatic carrier doping of Mott insulators, utilising field-effect transistor (FET) or electric double layer transistor (EDLT) structures to find novel superconductivity. We found the first field-induced superconductivity in an organic-based material in 2013 and has been developing various types of superconducting organic FETs. In this paper, our recent results on the development of novel photo-active superconducting organic FETs utilizing a photo-active electric double layer are summarized. We believe that the techniques and knowledge described here will contribute to advances in future superconducting electronics as well as the understanding of superconductivity in strongly correlated electron systems.
