New Generation

Basic and applied science of electroceramic thin films is an interdisciplinary field that is rapidly evolving worldwide. A major driving force for the extensive research in many university, industrial and national laboratories around the world is the promise of a new generation of advanced microdevices that may transform various technologies, potentially creating new multibillion-dollar markets. Electroceramic-thin-film properties that are being intensively investigated include electrical conductivity, large dielectric permittivity, ferroelectricity, piezoelectricity, pyroelectricity, and electro-optic activity. Perhaps the most publicized application of electrical conductivity of electroceramics is that related to the new high-temperature-superconducting (HTS) materials, which has been extensively discussed in numerous national and international conferences and in the scientific literature. Less glamorously publicized applications, but as important as those of HTS materials, are those involving ferroelectric materials, which is the subject of this MRS Bulletin.

ABSTRACTFerroelectric Bi4Ti3O12 thin films have been deposited using second harmonics of a Q-switched Nd:YAG laser. Various single crystal substrates, including SrTiO3(100), SrTiO3(110). MgO(100), and MgO(110), were used. Structural and electro-optic properties of the films were investigated using XRD, x-ray pole figure, and linear birefringence measurements. It is found that substrate kinds and their surface orientations are important growth parameters which determine crystal axis orientation and electro-optic properties of the Bi4Ti3O12 thin films.

Wide Range

Microstructure of epitaxial ferroelectric/conductive oxide heterostructures on LaAIO3(LAO) and Si substrates have been studied by conventional and high resolution transmission electron microscopy. The epitaxial films have a wide range of potential applications in areas such as non-volatile memory devices, electro-optic devices and pyroelectric detectors. For applications such as electro-optic devices the films must be single crystal and for applications such as nonvolatile memory devices and pyroelectric devices single crystal films will enhance the performance of the devices. The ferroelectric films studied are Pb(Zr0.2Ti0.8)O3(PLZT), PbTiO3(PT), BiTiO3(BT) and Pb0.9La0.1(Zr0.2Ti0.8)0.975O3(PLZT).Electrical contact to ferroelectric films is commonly made with metals such as Pt. Metals generally have a large difference in work function compared to the work function of the ferroelectric oxides. This results in a Schottky barrier at the interface and the interfacial space charge is believed to responsible for domain pinning and degradation in the ferroelectric properties resulting in phenomenon such as fatigue.
