Homework Help: Radius of the fermi sphere

  1. Mar 30, 2008 #1
    [SOLVED] radius of the fermi sphere

    1. The problem statement, all variables and given/known data
    On page 249 of ISSP, Kittel says that the radius of a free electron Fermi sphere is

    [tex]k_F = \left(3 \pi^2 n \right)^{1/3}[/tex]

    where n is the concentration of electrons.

    I don't know why that is true.

    EDIT: never mind; they derive that on page 138

    2. Relevant equations

    3. The attempt at a solution
