[Phys-L] Re: band gap and temperature

[Bernard Cleyet <anngeorg@PACBELL.NET>]

here's an article to add frustration:

According to the textbooks this dependence can be attributed to two mechanisms:  the changing of the lattice spacing as temperature changes and the electron-phonon interaction.  I am having trouble understanding the details of the latter and the textbooks I have seen are content to merely name the mechanism without specifically describing it.
