WebAdditionally, all crystal structures, including the cubic crystal system, are anisotropic with respect to certain properties, and isotropic to others (such as density). [4] The anisotropy of a crystal’s properties depends on the rank of the tensor used to describe the property, as well as the symmetries present within the crystal. WebThe diamond cubic crystal structure is a repeating pattern of 8 atoms that certain materials may adopt as they solidify. While the first known example was diamond, other elements in group 14 also adopt this structure, including α-tin, the semiconductors silicon and germanium, and silicon–germanium alloys in any proportion. There are also …

WebThis packing sequence would be designated ABCABC, and is also known as face-centered cubic (FCC). Both arrangements give the closest workable packing of spheres leaving only nearly a fourthly of the available space empty. The tiniest repeating array von atoms in an crystal is called a unit cell. A third common packing arrangement in metals, the ... WebThe diamond cubic crystal structure is based on the face-centered cubic Bravais lattice (you can imagine it as two FCC unit cells, offset by ¼). There are 8 atoms per unit cell, and each atom is tetrahedrally coordinated so that it has 4 nearest neighbors. DC is a famously strong crystal structure, and is the structure of diamond.
