High Current-Induced Electron Redistribution in a CVD-Grown Graphene Wide Constriction

Figure 4

The simulated images of the change in normalized charge density in the area ( = 1000 nm  ×   = 800 nm) obtained at the currents (a) , (b) , (c) , (d) , and (e) . The red arrow in (b) reveals the current ejected direction that is parallel to the wide constriction length .
