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 °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.
