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…
