The structure of this new crystalline phase was successfully determined by the high-resolution powder X-ray diffraction using synchrotron radiation (λ = 1.30 Å) (Fig. 2c, Supplementary Fig. 9), which revealed the presence of a complex cation of [2]2+ and two chloride ions in ...
Amorphous metalsare a relatively new class of alloy, originating in about 1960 with the discovery of thin metallic ribbons by splat cooling[1]. These are always alloys, and pure metal glasses have not yet been produced. As these alloys are non-crystalline, they have no dislocations, at least...

and widths of the G and D peaks. It is shown that the visible Raman spectra depend formally on the configu- ration of the sp 2 sites in sp 2 -bonded clusters. In cases where the sp 2 clustering is controlled by the sp 3 fraction, such as in as-deposited tetrahedral amorphous carb...
The reversible phase transitions in phase-change memory devices can switch on the order of nanoseconds, suggesting a close structural resemblance between the amorphous and crystalline phases. Despite this, the link between crystalline and amorphous tellu
