Because of the common oxidation states of group IV elements (+2 or +4) and group VI elements (-2), 1:1 and 1:2 are two typical stoichiometries found in the IV-VI compounds. Particularly, in the Pb-Te binary system, the 1:1 stoichiometric PbTe is believed to be the only stable compound. Herein, using evolutionary algorithms, density functional theory, a laser-heated diamond anvil cell, and synchrotron X-ray diffraction experiments, we discovered a novel Pb-Te compound with an unexpected stoichiom ...[more]
