i need our help to answer
this is the question in the solid state physics
i want to help me
what is the ratio of the lattice constant c and a for a hcp lattice?(1
supposing the atoms to be rigid spheres , what fraction of space is filled
by atoms in the primitive cubic ,fcc,hcp,bcc and diamond lattice?(2
3)
Draw the primitive unit cell within afcc lattice . what distinguishes this cell
from that of the rhombohedral bravais lattice?
