For a FCC crystal structure,
(a) Define three primitive vectors in the Cartesian Coordinatesin the most symmetrical form. The lattice constant of FCC is‘a’.
(b) From the above primitive vectors in the direct lattice,derive reciprocal primitive vectors in the CartesianCoordinates.
(c) What is the structure of the reciprocal lattice? What is thelength of the side of the cubic cell?
