Negative thermal expansion (NTE) is a counterintuitive physical phenomenon that the unit
cell volume of material usually contracts instead of expands upon heating. With two …

Most materials expand upon heating. However, although rare, some materials contract upon
heating. Such negative thermal expansion (NTE) materials have enormous industrial merit …

Negative thermal expansion was found for ZrW2O8 from 0.3 kelvin to its decomposition
temperature of about 1050 kelvin. Both neutron and x-ray diffraction data were used to solve …

Negative thermal expansion (NTE) is the phenomenon in which materials shrink rather than
expand on heating. Although NTE had been previously observed in a few simple materials …

There has been substantial renewed interest in negative thermal expansion following the
discovery that cubic ZrW 2 O 8 contracts over a temperature range in excess of 1000 K …

We report the discovery of a large negative thermal expansion (NTE) up to α=− 25× 10− 6
K− 1 (⁠ α⁠: coefficient of linear thermal expansion) in Ge-doped anti-perovskite manganese …

Negative thermal expansion (NTE) of materials is an intriguing phenomenon challenging the
concept of traditional lattice dynamics and of importance for a variety of applications …

Negative thermal expansion (NTE) materials have become a rapidly growing area of
research over the past two decades. The initial discovery of materials displaying NTE over a …

The vast majority of materials have a positive coefficient of thermal expansion and their
volume increases on heating. There has been considerable recent interest in materials …

Isostructural ZrW2O8 and HfW2O8 show strong negative thermal expansion from 0.3 K up to
their decomposition temperatures of approximately 1050 K. This behavior is especially …
