Computational study of (111) epitaxially strained ferroelectric perovskites BaTiO3 and PbTiO3

Riku Oja, Karen Johnston, Johannes Frantti +1

The phase transition behaviour of PbTiO3 and BaTiO3 under (111) epitaxial strain is investigated using density-functional theory calculations. From tensile strains of +0.015 to com…

Polymer adhesion: first-principles calculations of the adsorption of organic molecules onto Si surfaces

Karen Johnston, Risto M. Nieminen

The structures and energetics of organic molecules adsorbed onto clean and H-passivated Si(001)-(2 $\times$ 1) surfaces have been calculated using density functional theory. For benz…

Unusual behaviour of the ferroelectric polarization in PbTiO $_{3}$ /SrTiO $_{3}$ superlattices

M. Dawber, C. Lichtensteiger, M. Cantoni +5

Artificial PbTiO $_{3}$ /SrTiO $_{3}$ superlattices were constructed using off-axis RF magnetron sputtering. X-ray diffraction and piezoelectric atomic force microscopy were used to s…
