(Q4) (20 pts) Sommerfeld Expansion of the 2-Dimensional Fermi Gas The density of states for the 2-dimensional Fermi gas confined in an area A is a constant: A²N 4xmA g(e) where ep= Calculate the internal energy U and heat capacity Cy of this gas in the limit kTep using the Sommerfeld expansion. Use ep and the integrals: x²e² (ex + 1)20 Love Lo -dr = 3 dr = 1 (ex + 1)²°
