Inside Back Cover: The Orbital Origins of Chemical Bonding in Ge−Sb−Te Phase‐Change Materials (Angew. Chem. Int. Ed. 17/2022)

Angewandte Chemie International Edition, vol. 61

Abstract

Uncovering the peculiar chemical bonding of phase-change materials is essential for understanding their unique physical properties. For the first time ever, Richard Dronskowski and co-workers analyze in their Research Article (e202115778) the wavefunctions of these rather covalent materials in terms of interacting atomic orbitals, mirroring independent analyses of their projected force constants. All of these materials break the octet rule, clearly evidencing electron-rich multicenter interactions, similar yet different from the molecular case.
