Effects of Screening on the Thermal Resistivity And Compressibility Ratio of Metals

Abstract

Models for computing thermal resistivity, compressibility ratio, and screening parameter of metals was developed and used to study the effects of screening on the thermal resistivity and compressibility ratio of metals. The results obtained revealed that the thermal resistivity of metals increases with an increase in the electron gas parameter. It also increases with an increase in the screening parameter showing that the screening in metals affects the thermal resistivity of metals. The results obtained further revealed that thermal resistivity of metals increases with increase in temperature. On the compressibility ratio, the results obtained shows that the compressibility ratio decreases with an increase in the electron gas parameter. Also, the compressibility ratio decreases with an increase in the screening parameter.

Keywords: Thermal resistivity, compressibility ratio, screening, screening parameter and metals
