We were motivated in this work by the fact that the hexagonal structure of BCP could possibly result in heterogeneous patterns with nanoscale spacings that may offer new opportunities for achieving a selective sensing function. Graphene/BCP based FET device provide high sensitivity for hydrogen ions. Over months stability of the device empower the device for future applicability.
