Oxide materials exhibit a large variety of functional properties that are useful in a plethora of applications. Symposium G focused on oxide thin films that include dielectric or switching properties. Its program mirrored very well the strong worldwide search for high-K thin films for gate, memory, and on-chip capacitors, as well as the emerging field of functional thin films for MEMS. A complete session was devoted to the colossal effect of dielectric response in (Ca,Cu)TiO 3 , representing the major European research groups in this field. A comprehensive overview on this phenomenon was given by D Sinclair J Wolfman presented the latest results on CCTO thin films obtained by wafer scale pulsed laser deposition. A Loidl showed the analytical power of dielectric spectroscopy when covering the complete frequency range from 1–10 12 Hz, i.e. from space charge to phonon contributions at the example of CCTO. Another session was devoted to applications in non-volatile memories, covering various effects including ferroelectric and resistive switching, the complex behavior of oxide tunnel junctions (H Kohlstedt), the possibility to manipulate the magnetic state of a 2d-electron gas by the polarization of an adjacent ferroelectric gate (I Stolitchnov). Latest advancements in ALD processing for high-K thin films in dynamic RAM were reported by S Ramanathan. The advancement of piezoelectric PZT thin film MEMS devices was well documented by outstanding talks on their developments in industry (M Klee, F Tyholdt), new possibilities in GHz filters (T Matshushima), advancements in sol-gel processing (B Tuttle, H Suzuki), and low temperature integration approaches by UV light curing (S Trolier-McKinstry). Recent advances in incipient ferroelectric thin films and nano composites for tunable capacitors in microwave applications were present by A Vorobiev and T Yamada. Integrated electro-optics is another field to be conquered by thin film structures. The impressive progress made in this field was highlighted by P Günter. Many contributions were devoted to processing techniques, showing the increasing importance of CVD techniques to deposit for instance perovskite thin films (G Malandrino). Nevertheless, stunning results were obtained by a sophisticated MBE tool allowing for precise compositional control of individual oxide monolayers and thus enabling High-Tc supraconductivity in individual monolayers to be addressed (I Bosovic). Oxides do not only gleam with giant dielectric properties, giant electronic conduction (superconductivity), there is also a giant electro-caloric effect, as explained by Z Kutnjak. The symposium could take advantage of the EU projects NUOTO and CAMELIA that organized a joint session on giant K dielectrics to present their project results to the scientific and industrial community.
