Partial orbital hybridization in two-dimensional phases
What is it about?
The information on orbital hybridization is very important to understand the structural, physical, and chemical properties of a material. Results of a comparative first-principles study on the behaviours of orbital hybridization in the two-dimensional single-element phases by carbon, silicon, and germanium are presented.
Why is it important?
We demonstrate that the valence electronic orbital in the two-dimensional hexagonal crystals of Si and Ge shows sp3-like behaviour for the partial hybridization of s and pz, which leads to their different lattice configurations to graphene. The role of ?-bonds in stabilizing the flat configuration of graphene is also discussed.
