Aryl Functionalization as a Route to Band Gap Engineering in Single Layer Graphene Devices
Hang Zhang, Elena Bekyarova, Jhao-Wun Huang +5
Chemical functionalization is a promising route to band gap engineering of graphene. We chemically grafted nitrophenyl groups onto exfoliated single-layer graphene sheets in the fo…
