High resolution measurement of mode Grueneisen parameters in the negative thermal expansion material ZrW2O8

ZrW2O8 is the classic example of a material exhibiting negative thermal expansion (NTE), i.e. lattice shrinkage on warming. The origin of this behaviour has been controversial for a long time, but is widely believed to be intimately linked to the lattice dynamics. Recent ab-inito studies have suggested that there is no single phonon mode that is responsible for the NTE, rather a collection of low energy modes all contribute. These same ab-initio studies have been...
