Abstract

Abstract : V. V. Brus et al. report that the majority charge carriers in CPE‐PyrBIm4 /graphene heterobilayers 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 electron‐rich structural units in the CPE‐PyrBIm4 backbone and/or field‐effect doping due to interfacial electrostatic effects from adjacent ionic functionalities, as described in article number 1600515.
