Due 5pm on Friday Week 1

a) Assuming the Sommerfeld model, and starting from a sketch of allowed traveling wave states in k-space, show that n_3d = (k_F)³/3π².

b) Estimate n_3d and E_F for gold using physical/chemical parameters such as density and electron configuration.

c) A&M 2.1 (2-d problem) [two-dimensional electron gas]
