Comparative analysis of the atomic structure of crystalline and amorphous PbTiO3 on the basis of the molecular-dynamics simulation data

Amorphous materials based on perovskite ferroelectrics

“…It should be noted that estimates of correlation length l, reported in ref [4] and ref [20] for amorphous PbTiO3 are significantly different. The structure of crystalline and amorphous PbTiO3 also was studied by molecular dynamics modeling based on the model of hard ions using spherically symmetric pair interaction potentials [22]. Chapter 12 -Amorphous materials based on perovskite ferroelectrics region of small distances, the Born-Meyer formula was used to describe the repulsion potential.…”
