Question: ( 1 7 pt ) Face - centered cubic ( FCC ) is a Bravais lattice. Define the primitive vector, a 1 , a 2

(17 pt) Face-centered cubic (FCC) is a Bravais lattice. Define the primitive vector, a1,a2, and a3, using the x,y, and z axes shown to the right. Use the bottom left corner of the unit cell as the origin, O. The conventional FCC unit cell has 14 atoms. Define the position of each atom in terms of the primitive unit vectors, e.g., the origin is P0=0*a1+0*a2+0*a3.
