Top views and side views of (a) planar monolayers of TiSi2, CrSi2, MnSi2, and FeSi2; (b) buckled monolayers of VSi2, NbSi2, and MoSi2. The blue or red balls represent transition metal atoms and the yellow balls represent silicon atoms. The black rectangle represents the unit cell. The values of buckled height ( d ) for VSi2, NbSi2, and MoSi2 are 0.289, 0.756, and 0.647 Å respectively.[ 117 ]
