Materials with tunable thermal properties enable on-demand control of temperature and heat flow. Here, the authors demonstrate how thermal conductivity of an antiferroelectric solid can be bi-directionally switched to 10% lower and 25% higher values

The reduction in thermal conductivity is usually achieved by increasing the scattering rate or localization of heat carriers. Here, the authors propose a mechanism to suppress the thermal transport in amorphous systems such as SiTe binary alloys via

The physical properties of ovonic threshold switching (OTS) materials are of great interest due to the use of OTS materials as selectors in cross-point array nonvolatile memory systems. Here, we show that the topological constraint theory (TCT) of ch

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 excita
