Hi,
In the context of semiconductors, I was asked why the mass action law is not valid for very low temperatures. I thought that it was valid, since for very low temperature it holds the non-degeneracy condition [tex] E_g >> k_B T [/tex] (I think so...). But maybe for some other reason it breaks. Does someone know why??? Thanks!

I am not sure, but perhaps it is related to the behavior of electrons in the lattice, which becomes more prominent at lower temperatures (or low energies)?
