Octahedral tilt relaxation decoupled from lattice parameters in epitaxial perovskite oxide films

Epitaxial strain in perovskite oxide thin films is conventionally understood through lattice parameter modulation, characterized by the c / a ratio of the pseudocubic cell. However, internal atomic arrangements such as octahedral tilting can relax independently, a phenomenon that...

Structure-Guided Enhancement of High-Temperature Thermoelectric Performance in Molten-Salt-Derived Weathered Biotite for Waste-Heat Recovery

Abstract Thermoelectric materials capable of operating at 600–900 °C are attractive for recovering industrial and nuclear waste heat toward a carbon-neutral society. Here, we report the structure-guided enhancement of high-temperature thermoelectric performance in natural weather...
