Each atom in a diamond cubic crystal is tetrahedrally bonded to 4 other atoms, so there are 4 nearest neighbors (NNs). In other words, the coordination number (CN) is 4. The NN distance is , and the next-nearest neighbor (NNN) distance is , where a is the lattice constant (I’ll prove this below). See more The most notable material with a diamond cubic structure is, of course, carbon (in diamonds). The diamond cubic structure is tetrahedrally coordinated, which means that each atom has 4 … See more Using the standard hard sphere model, nearest-neighboring atoms touch–that means they have a distance of , where is the radius of the atoms. We know that the closest 2 atoms are … See more The diamond cubic crystal structure is an incredibly inefficient way to pack atoms, but it forms in atoms that form tetrahedral (4-way) bonds, like carbon. Although each atom is bonded only 4 times (instead of 12 as in close-packed … See more The atomic packing factor (APF) is the volume taken by atoms, divided by the volume taken by the whole unit cell.
