Extra diffuse scattering often observed from<br />
materials near phase transitions<br />
• Distribution of<br />
configurations at finite<br />
temperature<br />
– Mixed phases (1st order)<br />
• Extended displacements<br />
• High-pressure<br />
– higher-co-ordination<br />
– Longer NN bond distance<br />
– Smaller volume/atom<br />
