More Information
Summary:Ionic Diodes In article number 2404306, Yuya Ishizaki‐Betchaku, Shunsuke Yamamoto, Masaya Mitsuishi, and co‐workers demonstrated ultrathin ionic diodes with electrostatically heterogeneous hybrid interfaces consisting of negatively charged nanoporous SiO2 nanofilms and positively charged polymer layer‐by‐layer multilayers. The ionic diodes exhibited excellent ion current rectification properties by effective ion accumulation and depletion at the heterogeneous hybrid interfaces under low ionic strength and asymmetric pH conditions.
