## FCC Structure

The sample element is taken as Tungsten (W)

- Primitive Vectors:

A1 = ½ a Y + ½ a Z

A2 = ½ a X + ½ a Z

A3 = ½ a X + ½ a Y

- Basis Vector:

B1 = 0 (Al) (4a)

However in orthogonal unitcell:

A1 = a X

A2 = a Y

A3 = a Z

And the Basis vectors:

B1 = 0.0 0.0 0.0

B2 = 0.5 0.5 0.0

B2 = 0.0 0.5 0.5

B2 = 0.5 0.0 0.5
