At zero temperature, this quantity is equal to the Fermi level, and in semiconductors it lies halfway between the valence and conduction (*) bands. This quantity is zero for photons, and it can also be given as the derivative of the Gibbs free energy with respect to particle number. For 10 points— identify this thermodynamic quantity which represents the amount of energy needed to add another particle to a system.
At zero temperature, this quantity is equal to the Fermi level, and in semiconductors it lies halfway between the valence and conduction (*) bands.
