In a diamond carbon atom occupy fcc
WebJun 8, 2024 · The two elements right under carbon (silicon and germanium) in the periodic table also have the diamond structure (recall that these elements cannot make double bonds to themselves easily, so there is no graphite allotrope for Si or Ge). While diamond is a good insulator, both silicon and germanium are semiconductors (i.e., metalloids). Weblattices, with a basis of two identical carbon atoms associated with each lattice point one di splaced from the other by a translation of ao(1/4,1/4,1/4) along a body diagonal so we can say the diamond cubic structure is a combination of two interpenetrating FCC sub lattices displaced along the body diagonal of the cubic cell by
