Sketch a representation of the planes denoted below within the cubic unit cell and label any intersection with a cube edge that is different from 1 or 0. (Draw only a single representation of the plane, as more than one may be possible by way of translational symmetry). (10pts) x y z x y z x y z x y z x y z x y z a) ) 112 ( b) (240) c) ) 3 20 ( 2 Express the following planes drawn within a unit cell in terms of their Miller indices (Hint, use translational symmetry when necessary to identify the intercepts) (10pts) x y z x y z x y z x y z x y z x y z 3. Identify the directions K, L, M and N illustrated in the figure. (10pts) a b c a b c L M N K 4. For the hexagonal unit cells depicted below determine the MillerBravais indices for the planes in Figures (a) (c), as well as those of the directions U, V and W in Figure (d) (note U is perpendicular to axis a 3 , (20pts) 5. Aluminum has an atomic radius of 0.143 nm, an atomic weight of 26.98 g/mol, and it crystallizes in a Aluminum has an atomic radius of 0....
