Abstract
The present work considers an electron gas where ion contributions to the static potential may be neglected. The influence of temperature on the static potential and also on the screening length are derived. In the present contribution the temperature issue for a Fermi gas is treated in its non-relativistic as well as relativistic form. The effect of an extraneous ion in a degenerate Fermi plasma is analysed and a temperature dependent electrostatic shielding length in a degenerate Fermi plasma is determined.
