Medium-range structural order in covalent amorphous solids
@article{Elliott1991MediumrangeSO, title={Medium-range structural order in covalent amorphous solids}, author={Stephen R. Elliott}, journal={Nature}, year={1991}, volume={354}, pages={445-452} }
Despite their lack of long-range translational and orientational order, covalent amorphous solids can exhibit structural order over both short and medium length scales, the latter reaching to 20 Å or so. Medium-range order is difficult to measure experimentally and to interpret unambiguously, but a variety of techniques have allowed several types of characteristic structural ordering to be identified and their origin elucidated.

The experimental observations provide evidence of a structural link between the amorphous and crystalline phases in a Pd-Ni-P alloy at the medium-range length scale and suggest that it is the connectivity of the 6M-TTP clusters that distinguishes the crystalline and amorphou phases.
