In all cases, the position was essentially independent of the metal. The concept of fermi level is of cardinal importance in semiconductor physics. Each trivalent impurity creates a hole in the valence band and ready to accept an electron. Where will be the position of the fermi. The fermi energy or level itself is defined as that location where the probabilty of finding an occupied state (should a state exist) is equal to 1/2, that's all it is.

Fermi statistics, charge carrier concentrations, dopants. The topic is not so easy to understand and explain. The fermi level (i.e., homo level) is especially interesting in metals, because there are ways to change. For a semiconductor, the fermi energy is extracted out of the requirements of charge neutrality, and the density of states in the conduction and valence bands. It is well estblished for metallic systems.
