An … WebbThe lowest energy, marked n = 1, is the lowest energy possible for electrons in silicon. Allowed energies are labeled by this "principle quantum number" n, with n increasing as energy increases. We are following a fairly common convention of setting the energy to be zero when electrons just have enough energy to leave the atom.
