A newly fitted interatomic potential predicts that dislocations in KTaO3 dissociate into partials and prefer charge-neutral cores, matching electron microscopy and positioning KTaO3 as ductile but stiffer than SrTiO3.

Dislocations and plasticity of KTaO$_3$ perovskite modeled with a new interatomic potential
A newly fitted interatomic potential predicts that dislocations in KTaO3 dissociate into partials and prefer charge-neutral cores, matching electron microscopy and positioning KTaO3 as ductile but stiffer than SrTiO3.
