Our ambition is to explain or predict properties of defects in materials by computer simulations based on solid-state physics, statistical and materials mechanics.

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.
