Carbon based ballistic RF electronics

In the past decade the progresses in nanofabrication, modeling (from atomistic to mesoscopic scales), and advances in nanocharacterisation have triggered an entirely new class of nanodevices. Owing to their superior electrical and mechanical performances, carbon based meterials such as graphene and carbon nanotubes (CNTs) have played a central role in these groundbreaking developments. Among the many, one of the most relevant feature of these materials is the capability to allow room temperature ballistic transport. This feature enables yet more compact and yet more efficient RF circuits, endowed of higher current density, higher on/off ratio and higher fmax/ft ratios. In this talk the activities ongoing in this area will be outlined through an European perspective by focusing on some emblematic examples of graphene based ballistic devices.
