Nanophotonics has garnered intensive attention due to its unique capabilities in molding the
flow of light in the subwavelength regime. Metasurfaces (MSs) and photonic integrated …

A unified picture of different application areas for incipient metals is presented. This
unconventional material class includes several main‐group chalcogenides, such as GeTe …

Chalcogenide phase-change materials (PCMs), such as Ge-Sb-Te alloys, have shown
outstanding properties, which has led to their successful use for a long time in optical …

Phase-change materials are some of the most promising materials for data-storage
applications. They are already used in rewriteable optical data storage and offer great …

Abstract Surface phonon–polaritons (SPhPs), collective excitations of photons coupled with
phonons in polar crystals, enable strong light–matter interaction and numerous infrared …

The rapid growth of brain-inspired computing coupled with the inefficiencies in the CMOS
implementations of neuromrphic systems has led to intense exploration of efficient hardware …

Phase change materials are materials that exist in at least two structurally distinct solid
phases, an amorphous and one (or more) crystalline phases. Many materials display phase …

Present-day multimedia strongly rely on rewritable phase-change optical memories. We
demonstrate that, different from the current consensus, Ge2Sb2Te5, the material of choice in …

Localization of charge carriers in crystalline solids has been the subject of numerous
investigations over more than half a century. Materials that show a metal–insulator transition …

Phase‐change materials can rapidly and reversibly be switched between an amorphous
and a crystalline phase. Since both phases are characterized by very different optical and …
