In a diamond carbon atom occupy fcc
WebSep 16, 2024 · The unit cell of diamond can be described as an fcc array of carbon atoms with four additional carbon atoms inserted into four of the tetrahedral holes. It thus has the zinc blende structure described in Section 12.3, except that in zinc blende the atoms that compose the fcc array are sulfur and the atoms in the tetrahedral holes are zinc. WebCorrect option is B) Diamond has a ZnS type structure. the carbon atoms occupy all the fcc lattice points along with alternative tetrahedral voids . total no.of tetrahedral voids in fcc unit cell =8 Where carbon atom occupy only 4 of them . therefore percentage of tetrahedral voids occupied by carbon atom in diamond is 50 percent.
