▎ 摘　　要

The majority of charge carriers in conjugated polyelectrolyte (CPE)-PyrBIm(4)/graphene hetero-bilayers can be dynamically changed from electrons to holes, and vice versa, within a temperature range of 60 degrees C. Doping mechanisms under consideration include charge transfer from structural units in the CPE-PyrBIm(4) backbone and/or field-effect doping from adjacent ionic functionalities. A new concept of the graphene/CPE/Au thermobarristor is proposed and practically realized.
