Tuning the band gap of graphene nanoribbons synthesized from molecular precursors
Yen-Chia Chen,Dimas G. de Oteyza,Dimas G. de Oteyza,Zahra Pedramrazi,Chen Chen,Felix R. Fischer,Felix R. Fischer,Michael F. Crommie,Michael F. Crommie +8 more
TL;DR: A technique for modifying GNR band gaps via covalent self-assembly of a new species of molecular precursors that yields n = 13 armchair GNRs, a wider GNR than those previously synthesized using bottom-up molecular techniques is reported.
Journal ArticleDOI
Molecular bandgap engineering of bottom-up synthesized graphene nanoribbon heterojunctions

TL;DR: In this article, the authors demonstrate nano-scale chemically synthesized GNR field effect transistors, made possible by development of a reliable layer transfer process, and observe strong environmental sensitivity and unique transport behavior characteristic of sub-1'nm width GNRs.
