Control of Uniaxial Negative Thermal Expansion in Layered Perovskites by Tuning Layer Thickness

Control of Uniaxial Negative Thermal Expansion in Layered Perovskites by Tuning Layer Thickness

Uniaxial negative thermal expansion (NTE) is known to occur in low n members of the An+1BnO3n+1 Ruddlesden–Popper (RP) layered perovskite series with a frozen rotation of BO6 octahedra about the layering axis. Previous work has shown that this NTE arises due to the combined effects of a close proxim...
