Realizing negative thermal expansion over an extended temperature range in PbTiO3-based perovskites

Negative thermal expansion (NTE) is fascinating, as it involves a material’s volume contraction rather than expansion upon heating. Although NTE lattices typically have highly flexible frameworks, the magnitude of NTE is often very small, and they frequently exhibit a narrow temperature range for co...
