1. The problem statement, all variables and given/known data
That's basically the whole question in the title there, ie;
Derive an expression for the fermi energy of a 2d structure at 0 kelvin.


2. The attempt at a solution
Basically the first part of the question had us sketching the Fermi-Dirac distribution function at 0K for a 2D quantum structure which is fairly straightforward (f=1 up to E= Ef, 0 after that), and now we are meant to use that graph to come up with an expression for Ef, which I don't have a clue how to do. Could be that I don't have the Math background for it. Any help is appreciated.
