-First-principles total energy calculations describing the energetics of this transition (front left) reveal a diffusion barrier of no more than \unit[0.8]{eV} for the deviation out of the ground-state configuration.
-And indeed, in large systems consisting of six thousand C atoms incorporated into a Si host of a quater of a million of atoms, these transitions can be observed with increasing temperature as can be seen within the shaded regions of the radial distribution function of Si-C bonds (rear right) obtained by large-scale empirical potential molecular dynamics simulations.
