The structure of disordered materials is still not well understood because of insufficient
experimental data. Indeed, diffraction patterns from disordered materials are very broad and …

Historically, the application of phase‐change materials and devices has been limited to the
provision of non‐volatile memories. Recently, however, the potential has been …

Disentangling nucleation and growth in materials that crystallize on the nanosecond time
scale is experimentally quite challenging since the relevant processes also take place on …

Phase change materials are of great interest as active layers in rewritable optical disks and
novel electronic nonvolatile memories. These applications rest on a fast and reversible …

Discovery of the GeSbTe phase‐change alloy in particular along the GeTe–Sb2Te3 tie‐line
took place in the mid‐1980s. The amorphous alloys showed ideal properties, for example …

Phase change memory (PCM) based on chalcogenide compounds is considered to be an
excellent candidate for next-generation memory because of its high speed, low energy …

The structure of high-temperature liquids is an important topic for understanding the fragility
of liquids. Here we report the structure of a high-temperature non-glass-forming oxide liquid …

Phase‐change materials (PCMs) are widely used for data storage and in other functional
devices. Despite their seemingly simple compositions, these materials exhibit intriguing …

A dedicated apparatus has been developed for studying structural changes in amorphous
and disordered crystalline materials substantially in real time. The apparatus, which can be …

The local atomic structures of amorphous Ge-Sb-Te phase-change materials have yet to be
clarified and the rapid crystal-amorphous phase change resulting in distinct optical contrast …
