Abstract

The temperature dependence of the high-frequency polarizability in a degenerate electron gas is investigated. The calculation is performed by extending the RPA to the diagonal exchange terms. Contrary to the imaginary part of the polarizability which is expressed through a general formula valid in the whole temperature region, the real part is calculated retaining only quadratic ,terms in the temperature. The correction terms are of interest in semimetals and semiconductors with small carrier concentration.
