Researchers dynamically tune friction in graphene

The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers at the University of Illinois Urbana-Champaign led by Professor Rosa Espinosa-Marzal of the Department of Civil and Environmental Engineering. The work is detailed in the paper, "Dynamically tuning friction at the graphene interface using the field effect," published September 19, 2023, in the journal Nature Communications.
