Figure 4.3: (a) and (b) show the energy of the distorted structures (eV/atom)
with respect to the perfectly symmetrical 2H and 1T structures, respectively.
The white squares denote massive reconstructions upon relaxation thus leading
to structures not belonging to the 2H and 1T class of structures. All the
energies are in eV/atom. The figure has been taken from the Paper-2.
