Polarons in PbTiO3 ?
July 28, 2022
An Atomistic Investigation
The dissociation of short-lived excitons gives rise to free electrons and holes. If coupled with the motion of nuclei, these free charges get trapped at a lattice site and polarons form. Due to the involvement of lattice distortions in the formation of polarons, their lifetime exceeds that of excitons. In this study polaron formation and migration in PbTiO3 is addressed.
