TL;DR
This paper investigates the electrical resistivity behavior of substituted Ca-ruthenates, exploring mechanisms like Coulomb interactions and energy-dependent density of states to explain their wide temperature and conductivity range.
Contribution
It introduces a detailed analysis of resistivity in pseudoternary ruthenates considering Coulomb interactions and energy-dependent density of states, expanding understanding of their transport properties.
Findings
Resistivity follows Efros-Shklovskii mechanism due to Coulomb interactions.
Unusual temperature and conductivity range explained by additional energy-dependent density of states.
Chemical substitution affects transport mechanisms in Ca-ruthenates.
Abstract
The temperature dependence of the electrical resistivity of two chemically substituted Ca-ruthenates is examined with the Efros-Shklovskii mechanism invoking Coulomb interactions between carriers. Additional mechanisms causing an energy dependence to the density of states at the Fermi surface may explain the unusually wide temperature and conductivity range obeyed by one system.
