Both arrangements produce a face-centered cubic lattice - with different orientation to the ground.
Pure copper, amongst other materials, forms a face-centered cubic lattice.
However, at pressures in excess of 1 Mbar it is predicted that the structure would shift to a more stable face-centered cubic lattice.
Each central sphere can have up to twelve neighbors, and in a face-centered cubic lattice these take the positions of a cuboctahedron's vertices.
As in the rock-salt structure, the two atom types form two interpenetrating face-centered cubic lattices.
Fortran code for the three-dimensional Ising model on body-centered cubic and face-centered cubic lattices.
The mercury atoms form linear sp bonds, while the nitrogen forms tetrahedral sp3 bonds, in a face-centered cubic lattice.
This polyhedron in a space-filling tessellation can be seen as the Voronoi tessellation of the face-centered cubic lattice.
HgCdTe has a zincblende structure with two interpenetrating face-centered cubic lattices offset by (1/4,1/4,1/4)a in the primitive cell.
In three dimensions, the face-centered cubic lattice offers the best lattice packing of spheres, and is believed to be the optimal of all packings.
Explicit calculations are made of these terms for the simple cubic, body-centered cubic, and face-centered cubic lattices, with both first- and second-neighbor interactions.
For instance, the face-centered cubic lattice and its higher-dimensional generalizations, the D lattices, consist of all of the integer points whose sum of coordinates is even.
Accordingly, the rhombic dodecahedral honeycomb is the Voronoi tessellation of the D root lattice (a face-centered cubic lattice).
For example, NaCl can be described as close-packed chloride ions (in a face-centered cubic lattice) with sodium ions in the octahedral holes.
In the rock-salt or sodium chloride (halite) structure, each of the two atom types forms a separate face-centered cubic lattice, with the two lattices interpenetrating so as to form a 3D checkerboard pattern.
In the face-centered cubic lattice Si centers occupy the corners and face-centered positions of the unit cell and Mg centers occupy eight tetrahedral sites in the interior of the unit cell.
In 2013 Hugh F. Wilson, Michael L. Wong, and Burkhard Militzer at the University of California, Berkeley published a paper predicting the face-centered cubic lattice structure that would emerge at higher pressures.
The IVM scaffolding or skeletal framework was defined by cubic closest packed spheres (CCP), alternatively known as the FCC or face-centered cubic lattice, or as the octet truss in architecture (on which Fuller held a patent).
This example is readily extended to three dimensions, for example, to a body-centered cubic or face-centered cubic lattice by introducing the nearest neighbor vector locations in place of simply n a. Likewise, the method can be extended to multiple bands using multiple different atomic orbitals at each site.
