Die Aktivitäten des ER-C-2 zielen darauf ab, ein Verständnis der Strukturen, Eigenschaften und grundlegenden Mechanismen von strukturellen, funktionellen und elektronischen Materialien auf atomarer Ebene zu schaffen. Ein besonderer Schwerpunkt liegt auf Systemen zur Energiegewinnung, Energieumwandlung und Energiespeicherung. Weitere Anwendungsbereiche sind hochfeste Stähle, Leichtbaumaterialien für den Transport, funktionelle Grenzflächen in Verbundwerkstoffen und Biomaterialien und ihre technologischen Gegenstücke.

Weg zu weiterer Miniaturisierung von FeRAM

Jülich / Aachen, 2 February 2021. Ferroelectric Random Access Memory, or FeRAM for short, offers both working memory and data storage in one. This saves on the time and energy needed by conventional computers to transport data between the two units. In addition, the saved data is retained even without a power supply. The write performance and service life of these components are already outstanding and the first FeRAMs are already in use, for example in chip cards or RFID tags. However, comparatively small amounts of data can as yet be stored on a FeRAM, as the space required for storing individual bits is too large.

PGI Kolloquium: Prof. Dr.-Ing. Ulrich Kunze, Ruhr University Bochum, Bochum, Germany

Full-wave rectification is a phenomenon that has been known for many years in micro- and nanoscale three- and four-terminal semiconductor structures. A number of effects were identified as the origin, most of which are based on symmetry breaking of the device structure. After some comments on the fabrication technology, this lecture will address them individually on the basis of experimental results and relate them to critical transport parameters.
