On the Density of Electronic States of Liquid Mercury

Abstract

The density of electronic states have been calculated for liquid mercury based on the perturbation theory by using the non-local energy dependent Evans model potential. The result at 20°C shows a modest dip below the Fermi level. Though a shallow dip is evidently observed at 200°C, there is a tendency for the dip to disappear at higher temperature. This calculation shows that it is important to include the non-locality of the modal potential in liquid mercury. a good agreement between experiment and calculation was found in the electrical resistivity and thermoelectric power over a wide temperature range.
