Problem 1.
a) Derive the expressions for the Fermi energy, Fermi velocity, and electronic density of states for a two-dimensional free electron gas.
b) A 2D electron gas formed in a GaAs/AlGaAs quantum well has a density of . Assuming that the electrons there have the free electron mass, calculate the Fermi energy and Fermi velocity.
