Theoretical calculation of transport properties of oxide material using narrow band model

Abstract

We report about the results of theoretical calculations of temperature dependence of resistivity ($\rho$) and Seebeck coefficient ($S$) for thermoelectric (TE) and superconductivity (SC) phases by arithmetic equations based on narrow band model with oxygen deficient structure, as the functions of band-filling degree ($F$), and band width ratio of electron and spin states ($W$\sigma/$W$D). The phase diagrams of TE and SC states, and boundary were imaged to the properties of $\rho$ and $S$ as a function of $F$ and $W$\sigma/$W$D.
