Abstract

In article number 2005533, Matthias Wuttig and co-workers study systematic changes of chemical bonding in lead chalcogenides (PbX, where X = Te, Se, S, O) to comprehend their properties. They discover an electron-transfer-driven transition from highly anharmonic, metavalent bonding in thermoelectric PbX (X = Te, Se, S) to iono-covalent bonding in β-PbO, highlighting the relevance of the concept of metavalent bonding for materials design.
