12. The figure at left below shows the band diagram of single sheet of graphite, also known as graphene, which is a semimetal. Notice that the valence band is full, the conduction band is empty and there is no band gap as the two bands touch at the Fermi level. A boron-carbon graphite has the same planar structure as graphene shown in the schematic below (boron occupies substitutional sites in the graphite sheet. (a) Please identify (draw) the unit cell and determine the composition of the BxCy graphite. СВ EF (b) What is the hybridization of the B and C atoms? B N(E) (b) Draw a schematic of the band structure for the materials using that of graphene as a guide. Show the VB the CB and the Fermi level and indicate whether this material is metal, semiconductor or semimetal (explain).
