Residual Resistivity of Some Metallic Elements

Aditya M. Vora

Abstract


In the present article, the residual resistivity of some metallic elements of the periodic table is reported on the basis of model potential formalism. Ashcroft’s well known empty core (EMC) model potential is explored first time with five different types of the local field correction functions proposed by Hartree (H), Taylor (T), Ichimaru-Utsumi (IU), Farid et al (F) and Sarkar et al (S) to investigate the effect of the exchange and correlation on the aforesaid properties. The comparisons of presently computed results are found in qualitative agreement with available theoretical and experimental findings. Present investigation of the residual resistivity is found to be quite sensitive to the selection of local field correction function and showing a significant variation with the change in the function.
