6. (pt 30) A two-dimensional metal has one atom of valency one in a simple rectangular primitive cell a=2 A and b-4 A. (a) (pt 10) Calculate the radius of the free electron Fermi sphere in cm¹ (empty lattice approximation) (b) (pt 10) Draw this sphere to scale on a drawing of the reciprocal lattice (empty lattice approximation) (c) (pt 10) Sketch another to show the first few periods of the free electron band in the periodic zone scheme, for both the first and second energy bands. Assume that there is a periodic potential.
