Equilibrium heating of rod 2624


Radius of Gyration

Gold nanorod with 2624 atoms have been through constant temperature MD from 100K to 1200K with the step of 100K and equilibrating for 10^7 steps (43ns) at each temperature. The radii of gyration of each temperature have been concatenated in one plot. Each piece is the equilibration at the temperature specified left.

The radius of gyration from the simulation of continuous heating of rod 2624 has also been put on the plot for comparison. Note the temperature of this plot is continuous.


Side Equilibrium Shape

At each temperature of the equilibrium heating, the side atoms have been projected in 2D along z axis with the edges cut off. All the positions of the atoms have been averaged by the circular angles.
