Germanium Telluride (GeTe) can be described as a non-volatile (latching state) phase change material (PCM) in memory applications. GeTe also exhibits a volatile (reversible state) region when heated and cooled between 100-180 ℃. At temperatures higher than 185 ℃ the material ...
To obtain a more advanced functionality at high temperatures (as opposed to the bright-field imaging demonstrated here), the metasurface must support a nontrivial angle-dependent transfer function also when the PCM has transitioned to the high-temperature state. In the current experiment, the angle...

Phase change memory (PCM) is a rapidly growing technology that not only offers advancements in storage-class memories but also enables in-memory data processing to overcome the von Neumann bottleneck. In PCMs, data storage is driven by thermal excitation. However, there is limited research regardin...
(PCMs) are materials that can hold and release heat irreversibly upon little temperature variation. PCM absorbs and releases energy in the form of latent heat, which is usually more significant as compared to sensible heat, and at lower temperature difference as a driving force for the heat ...
PCM alloy used in the devices, Ge2Sb2Se4Te (GSST), uniquely combines giant non-volatile index modulation capability, broadband low optical loss and a large reversible switching volume, enabling notably enhanced light–matter interactions within the active optical PCM medium. Capitalizing on these ...
Therefore, solid−liquid phase transformation can be combined with air cooling to achieve better cooling effect. The integration of PCM and cold−board has great prospect, which not only keeps the inner temperature in the working range, but also enhances the homogeneity of the inner temperature...
PCM can store a huge amount of energy with low or no temperature swing. However, the major drawback of PCM is the low thermal conductivity. Techniques of different scales (macroscopic, microscopic and nanoscopic) have been adopted in thermal engineering to enhance the thermal conductivity of PCM...

Phase change is a phenomenon that occurs in a fibrous medium as a result of sorption/de-sorption of fiber moisture, condensation/evaporation of moisture in the void place, and melting/solidification of PCM when incorporated into the fabric structure. Both melting/solidification of PCM and sorption...
