# Exercise 2.1-1 Free Electron Gas with Constant Boundary Conditions

| Consider the free electron gas model but let the boundary conditions be: y(0) = y(L) = 0, i.e. we have fixed boundary conditions.
|  | Derive the solution to the Schrödingerequation and the density of states for this case.
|  | Show that the number of states is the same as for the periodic boundary conditions as given in the backbone
| Link to the solution
