Abstract

'Improper' ferroelectricity In the field of 'oxide electronics', artificially layered structures based on thin films of complex oxides are designed to obtain novel, technologically interesting electric or magnetic properties. Bousquet et al. studied artificial superlattices made from ferroelectric (PbTiO3) and paraelectric (SrTiO3) oxides. They have found a previously unknown type of atom rearrangement at the interfaces between thin films of these materials, leading to an unusual 'improper' ferroelectric effect. The system has a very large dielectric constant that, unlike conventional ferroelectricity, is fairly temperature independent. This is of considerable technological interest as a route to improved materials for high-permittivity dielectric layers in traditional microelectronics as well as for emerging needs in magneto-electric applications.
