Figure 4
Density plots of the WFCs for selected Pb atoms corresponding to six equivalent Pb1 sites in the supercell of the MD trajectories calculated at 123, 273, 293 and 393 K. The plots show the density distribution (x versus z coordinates) of the WFCs extracted from MD trajectories in steps of 100 fs. The WFCs coordinates are expressed as a difference with respect the reference Pb coordinates. |
