Calculating Effective Mass

  1. Oct 6, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider electrons in a Kronig-Penney model with the following parameters:
    a=b=3 angstroms
    Uo=10.0 eV

    Calculate the effective mass of the electrons near the start of the first allowed band.

    You can find this by fitting the E-k results to an equation

    E=E1+(hbar^2 x k^2)/(2m*) where E1 is the start of the first allowed band.

    2. Relevant equations



    3. The attempt at a solution

    I have no clue where to start. Since I'm trying to find m*, it will probably be in relation to E, so how do I calculate E from the given values?
