The face-centered cubic lattice contains an atom in each of the face of the cube and an atom in each of the corners.
Step 1: Determine how many atoms are present in 1 unit cell.
In a unit cell: atoms have different contribution depending on their location
corner atoms 1/8
atoms in center 1
atoms in face of the cube 1/2
If the quantum dot is shaped like a cube, how many of each type of atom are there in a cubic crystal with edge length of 3.00 nm?
