Substrate effect on charging of electrified graphene/water interfaces
Yongkang Wang, Yuki Nagata, Mischa Bonn
Abstract
Surface-specific spectroscopy study of buried graphene electrodes, supported on different substrates, reveals that graphene charging is decoupled from the charging of its substrate. The substrate governs the reorganization of interfacial water.
