Enhanced Thermoelectric Performance in Oxide Composites of La and Nb Codoped SrTiO3 by Using Graphite as the Electron Mobility Booster

“…Interestingly, these doped STOs show very poor conductivity in spite of having a large electron concentration. It is more likely that Anderson localization of electrons is present in these complex oxides due to variations in local electrical fields created by lattice defects, as reported by many in the literature. − However, the presence of graphite helps those electrons to become delocalized and causes a manifold increment in weighted mobility of electrons resulting in enhanced electron transport.…”

Effects of iron substitution and anti-site disorder on crystal structures, vibrational, optical and magnetic properties of double perovskites Sr2(Fe1−xNix)TeO6

“…Among many, these include half-metallicity and ferromagnetism for spintronics, 4,5 semiconductivity for photocatalytic water oxidation 6,7 or piezoand ferroelectricity for photovoltaic solar cells. 8,9 It is not surprising that perovskites and related superstructures continue to be attractive for research over many decades of study.…”

High-Entropy Perovskites: An Emergent Class of Oxide Thermoelectrics with Ultralow Thermal Conductivity

“…As a result, itinerant electrons can become localized, which is called Anderson’s localization. Such kind of behavior has been reported in the literature for perovskites − and double perovskites. − It is believed that the presence of five different transition metals possessing multiple oxidation states caused the Anderson localization of charge carriers in HEPs. Hence, HEPs were not found to follow the degenerate Fermi gas model in the temperature-dependent electrical conductivity behavior.…”
