How to add a corresponding statement to the code, to display the position of Fermi level in the structure?

Muhammad Hamza El-Saba

Tne Fermi level is formally defined in Equilibrium, where there is no bias.

However, you can still plot the so-called quasi-Fermi levels, using their definition

Efn = Ei + kB.T ln (n/ni),

Efp = Ei - kB.T ln (p/ni)
