Figure 2From: Evidence for formation of multi-quantum dots in hydrogenated grapheneColor scale plot of the conductance G versus V BG and V SD . Shown at (a) T = 5 K and (b) T = 10 K. The back gate voltage swept from 40 to 45 V at a step of 100 mV. The irregular feature of the Coulomb blockade region in Figure 2a suggests a multi-quantum dot formation.Back to article page
