Graphene Nanoribbons for Electronic Devices

TLDR: In this article, the suitability of graphene nanoribbons devices for nanoelectronics was discussed and three specific device types were discussed: MOSFETs, side-gate transistors, and three terminal junctions.

Abstract: Graphene nanoribbons show unique properties and have attracted a lot of attention in the recent past. Intensive theoretical and experimental studies on such nanostructures at both the fundamental and application-oriented levels have been performed. The present paper discusses the suitability of graphene nanoribbons devices for nanoelectronics and focuses on three specific device types – graphene nanoribbon MOSFETs, side-gate transistors, and three terminal junctions. It is shown that, on the one hand, experimental devices of each type of the three nanoribbon-based structures have been reported, that promising performance of these devices has been demonstrated and/or predicted, and that in part they possess functionalities not attainable with conventional semiconductor devices. On the other hand, it is emphasized that – in spite of the remarkable progress achieved during the past 10 years – graphene nanoribbon devices still face a lot of problems and that their prospects for future applications remain unclear.
