We present an overview of charge transport in selected one‐, two‐ and three‐dimensional carbon‐based materials with exciting properties. The systems are atomically defined bottom‐up synthesized graphene nanoribbons, doped graphene and turbostratic graphene micro‐disks, where up to 100 graphene layers are rotationally stacked. For turbostratic graphene we show how this system lends itself to spintronic applications. This follows from the inner graphene layers where charge carriers are protected and thus highly mobile. Doped graphene and graphene nanoribbons offer the possibility to tailor the electronic properties of graphene either by introducing heteroatoms or by confining the system geometrically. Herein, we describe the most recent developments of charge transports in these carbon systems. This review describes the properties of carbon allotropes from 1D graphene nanoribbons to 2D doped graphene and 3D turbostratic graphene micro‐disks. While turbostratic graphene lends itself to spintronic applications resulting from protected graphene layers, where charge carriers are highly mobile, doped graphene and graphene nanoribbons offer the possibility to tailor the electronic properties by introducing heteroatoms and using geometrical confinement.
