order-disorder transition

order-disorder transition

[′ȯrd·ər ′dis‚ȯrd·ər tran′zish·ən]
(solid-state physics)
The transition of an alloy or other solid solution between a state in which atoms of one element occupy certain regular positions in the lattice of another element, and a state in which this regularity is not present.

Above the bulk order-disorder transition temperature (Todt) of symmetric polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA), the mismatching of film thickness and bulk periodicity result in the hierarchical formation, ranging from spinodal morphology to islands/holes [2, 17].

The order-disorder transition is thermodynamic in nature which is controlled by physical factors; energetics and entropy.
It would be a useful application of AES if the lineshape can be correlated to surface structural changes, either to order-order or to order-disorder transitions. This is the main issue of this work.

Finally, one should note that a great variety of magnetic materials including halides, metals, oxides, intermetallics, and sulphides exhibit anomalies in their elastic properties due to the fact that order-disorder transitions are typically accompanied by small lattice distortions [17].
