(a) Schematic of the simulation model for the Müller–Plathe RNEMD method. Heat flux was established between the hot and cold regions. Periodic boundary conditions were applied in the x and y directions. (b) Typical temperature profile in a ZGNR along the x direction at 300 K and the temperature gradient calculated by the linear response region of the temperature profile.
