Homework Statement
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.
Homework Equations
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?
