Figure 4.1: (a), (f) show the 1T undistorted 1T and 2H structures respectively.
Yellow spheres represent the chalcogen atoms and the cyan spheres represent
the metal atoms. (b) - (e) show the distortions in the 1T structure. The unit
cell of the distorted structure is shown with black solid lines and the distortion
of the atoms from their ideal symmetric position is shown with black dotted
lines. (g) represents the distorted 2H structure with a similar description as
above. The figure has been taken from the Paper-2.
