HOw od you calculate the planar density for {100}, {110}, {111} for FCC?
Planar density is a measure of the number of atoms per unit area in a crystal lattice.
The formula for calculating planar density for FCC crystals is: PD = 4N / a^{2}, where PD is the planar density, N is the number of atoms in the unit cell, and a is the lattice constant.
The number of atoms in a FCC unit cell is determined by multiplying the number of atoms at each lattice point (4) by the number of lattice points within the unit cell (1).
The three most common {hkl} planes for FCC crystals are {100}, {110}, and {111}.
To calculate the planar density for specific {hkl} planes in FCC crystals, you can use the formula PD = (h^{2} + k^{2} + l^{2}) / a^{2}, where h, k, and l represent the Miller indices for the plane and a is the lattice constant.
