The unit cell of an fcc lattice has right angles, and each face has gold atoms touching each other along the diagonal (usually the diagonal is depicted as running from the center of one atom, through the center of a second atom, to the center of a third atom). Thus, one can draw a right triangle whose legs both have length of a = 0.40788 nm and whose hypoteneuse is 4r, where r is the radius of a gold atom. By the Pythagorean theorem: a2 + a2 = (4r)2 2a2 = 16r2 r = (21/2/4)a Substituting in a = 0.40788 nm, r = 0.14421 nm, which is the listed covalent atomic radius of gold. Please note that this method only works when considering lattices composed of a single element. When multiple elements are involved, their radii change due to interaction with the other elements.
(Lattice constant of film / Lattice constant of substrate)-1 few people also define it as, (Lattice constant of substrate / Lattice constant of film)-1 [Faux et al. JAP94]
It's a crystal lattice or lattice structure
Lattice is imaginary set of points in space from which the crystal structure is constructed by adding basis to each point
crystal lattice is the orientation of atom in uniform manner with same characterized.where as space lattice is the three dimensional orientation of atom with different existing property.
Lattice basically refers to the shape of the given crystals based on their structures.
For all BCC lattice structures, the Lattice constant (a) can be found by : a = (4r) / sqrt(3)

a=5.462 for CaF2
The lattice constant is 5,65 angstroms.

In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier Transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum space or less commonly k-space, due to the relationship between the Pontryagin momentum and position. The reciprocal lattice of a reciprocal lattice is the original or direct lattice.
Coroot lattice is a type of lattice that is used in trellises. The pattern of coroot lattice resembles a checkerboard.
A lattice point represents a constituent particle in a crystal lattice and when lattice points are joined by straight lines, they bring out the geometry of lattice.
This lattice is orthorombic.
