โœฆ Synopsis

It is shown that the electrical conductivity, thermal conductivity and thermoelectric effects in metals and polar semiconductors can be expressed by formulae which appear as natural extensions of the elementary theory valid for those circumstances for which a "universal" relaxation time can be defined. The formulae involve two formal relaxation times, which coalesce when a universal relaxation time exists.
