Graphene nanoribbons are the basic element of many nanoscale devices. Numerous studies have already been performed on fundamental research to explore their properties from theoretical and experimental points of view. With applicative studies now taking over the fundamental studies, leading editors and authors in the field review the fundamental properties and the current device technology in this book.
Theoretical properties of graphene nanoribbons are introduced before concentrating on different fabrication methods and their properties out of different experimental characterizations. Finally, the text explores the perspectives of graphene nanoribbons for electronic transport.
This is a one-stop handbook for researchers wanting to further utilise graphene nanoribbons, and it is also a valuable reference text for any interested materials and surface scientists.
