SUMMARY:Emergent Iontronics
DESCRIPTION:Yoshihiro Iwasa\, Department of Applied Physics and Quantum-P
 hase Electronics Center\, University of Tokyo\, JapanIn your mobile phone
 s\, there are two kinds of important devices\, billions of transistors and
  a battery. The transistor controls electron flow in a semiconductor to en
 able processing and storage of information\, while the latter stores elect
 rochemical energy for driving the former. In the latest decade\, devices w
 ith combined concepts of transistors and batteries\, electrochemical trans
 istors\, are receiving increasing interests\, because they can offer new o
 pportunities beyond conventional current switching functions of all solid 
 transistors.One of surprises comes from a simple replacement of solid gate
  dielectrics in field effect transistors (FETs) with electrolytes\, which 
 produces an innovative concept of field effect phase control in a variety 
 of materials\, including superconductors\, ferromagnets\, Mott insulators\
 , and even metals. Current status of emergent “iontronics”\, electroni
 cs based on ionic functions\, will be reviewed.References[1] M. Kawasaki a
