We report the realization of graphene nanoribbon (GNR) transistors with I-ON/I-OFF ratio of 2 x 10(7) and electron and hole mobilities of 400 cm(2)/V.s and 1100 cm(2)/V.s respectively at 6 K. The nanoribbons were fabricated by Pt catalyzed etching of mechanically exfoliated graphene in hydrogen ambient. The performance parameters obtained are some of the best values ever reported. The high performance indicates the highly smooth edges along crystallographic directions in GNR obtained by the catalytic etching process. (C) 2018 Elsevier Ltd. All rights reserved.
