Abstract
We investigate the effects of band filling as well as temperature change on the electrical conductivity of materials with strong interelectron interaction as well as band hybridization. This is done by use of the irreducible two-particle Green function method applied to strongly correlated electron systems described by the Periodic Anderson Model. It was found that there is a definite peak in electrical conductivity at low band occupancy when the d-energy sub-band is half filled. Conductivity was found to have a sharp drop with an increase in temperature as a result of thermal dispersion as well as a change in the width of the narrow energy sub-bands causing an increase in the number of charge carriers with negative effective mass.
