Very recently, it was demonstrated explicitly that a zigzag graphene nanoribbon (GNR) exhibits a crossover of conductance from G0 to G0/2 with increasing the length (G0 = 2e2/h is the quantum of conductance) even at room-temperature…

One notable manifestation of the peculiar edge-localized states in zigzag graphene nanoribbons (zGNRs) is the p-type (n-type) characteristics of nitrogen (boron) edge-doped GNRs, and such behavior was so far considered to be exclusive for…
