Ferroelectricity and antiferroelectricity in the BaS-PbS system with the rocksalt structure
Alexander I. Lebedev
First‑principles DFT calculations reveal that introducing Ba into the rocksalt BaS‑PbS system induces transverse‑optical phonon instabilities, leading to competing ferroelectric, a…

EXAFS studies of the local environment of lead and selenium atoms in PbTeSe solid solution
A. I. Lebedev, I. A. Sluchinskaya, V. N. Demin +1
EXAFS spectroscopy is used to study the local environment of lead and selenium atoms in PbTeSe solid solution. In addition to a bimodal distribution of bond lengths in…
