Journal ArticleDOI
Phase-change materials for rewriteable data storage
Matthias Wuttig,Noboru Yamada +1 more
TL;DR: This review looks at the unique property combination that characterizes phase-change materials, in particular the contrast between the amorphous and crystalline states, and the origin of the fast crystallization kinetics.
Journal ArticleDOI
Resonant bonding in crystalline phase-change materials
TL;DR: Measurements of the dielectric function in the energy range from 0.025 to 3 eV reveal that the optical dielectrics constant is 70-200% larger for the crystalline than the amorphous phases.
Journal ArticleDOI
Phase-change materials for non-volatile photonic applications
TL;DR: Materials whose optical properties can be reconfigured are crucial for photonic applications such as optical memories and phase-change materials offer such utility and recent progress is reviewed.
Journal ArticleDOI
Structural transformations of Ge2Sb2Te5 films studied by electrical resistance measurements
TL;DR: In this paper, temperature dependent measurements of the electrical resistance have been employed to study structural changes in sputtered Ge2Sb2Te5 films, which enable a precise determination of transition temperatures and activation energies.
Journal ArticleDOI
A map for phase-change materials.
Dominic Lencer,Martin Salinga,Blazej Grabowski,Tilmann Hickel,Jörg Neugebauer,Matthias Wuttig +5 more
TL;DR: A first treasure map for phase-change materials is presented on the basis of a fundamental understanding of the bonding characteristics, spanned by two coordinates that can be calculated just from the composition, and represent the degree of ionicity and the tendency towards hybridization ('covalency') of the bonded materials.
