Evidence for resonant bonding in phase-change materials studied by IR spectroscopy

Abstract

Phase-change materials (PCM) attract attention due to their unique properties. This remarkable portfolio also makes them promising for applications in novel data storage devices. In this study, we discuss differences in the optical properties of PCM and non-PCM in the IR caused by presence or absence of resonant bonding.
