specic heats. As already mentioned, the low temperature behaviour of the specic
heat of electron gas has a linear dependence in T, and therefore the Debye theory has
to be modied for metallic solids. We give some important, and essential, results for
the Debye theory. Further discussion of the Debye theory can be found in chapter
15. Just as in the Einstein theory, in Debye theory too there is a characteristic Debye
