please answer b,c,d Draw FCC structure By considering the packing of atoms along the diagonal of one face of the cubic structure, find the relationship between the atom radius r and the lattice parameter a. Calculate the number of atoms per lattice (N) for the FCC structure. Calculate the atomic packing factor (APF) for the FCC structure.
Q3. The surface energy of a new surface can be calculated based on the equation discussed in class: Where Nb is the number of bonds broken to create the surface, pa is the number of atoms per unit area of the new surface and ε is the bond strength. Considering an FCC structure with a lattice constant of a, using this equation the surface energy of different facets (or crystal planes) can be calculated For the (100) plane this was...
