Lay Summary (German)

Lead
Schichten oxidischer Materialien können inzwischen mit ähnlicher atomarer Präzision gewachsen werden, wie Halbleiternanostrukturen. Im Gegensatz zu Halbleitern zeigen Oxide aber zusätzliche Effekte, die auf starken Wechselwirkungen zwischen den Elektronen beruhen. Viele davon betreffen die Leitfähigkeit oder die Kopplung magnetischer und elektrischer Eigenschaften und sind daher für Anwendungen äusserst interessant. Das Potenzial derartiger Systeme ist jedoch bei Weitem noch nicht ausgeschöpft.
Lay summary
Ziel unseres Projektes ist es, neue Klassen von multifunktionaler Oxidheterostrukturen herzustellen und zu charakterisieren. Zum einen sollen dies Systeme sein, in denen die magnetischen Eigenschaften mittels elektrischer Spannungen (statt über magnetische Felder) kontrolliert werden. Dies würde den Energieverbrauch entsprechender Bauteile drastisch verringern und aufgrund der geringen Abwärme deren Miniaturisierung begünstigen. Zum anderen sollen oxidische Multilagen eingesetzt werden, um die Funktionalität von Mikrofestbrennstoffzellen und magnetoresistiven Speicherelementen grundlegend zu steigern. Hierbei sollen insbesondere auch die besondere Eigenschaften der Grenzfläche zwischen Materialien ausgeschöpft werden.

Das Projekt hat zwei Ansatzpunkte. In Hinsicht auf die Grundlagenforschung sollen prinzipielle Erkenntnissen zu den Gesetzmässigkeiten der Wechselwirkung zwischen magnetischen und elektrischen Eigenschaften oxidischer Materialien gewonnen werden. In Hinsicht auf Anwendungen sollen diese Eigenschaften zu neuen Bauteilen in der Oxidelektronik führen. Hierbei soll die Energieeffizienz im Vordergrund stehen, wobei sowohl ein geringerer Energieverbrauch als auch die verbesserte Energiegewinnung, etwa durch Einsatz transparenter Elektronik, angestrebt werden.

Abstract

The PIs propose to uncover novel functionalities in oxides by applying high-end structuring techniques to two prominent families of oxide compounds. In order to emphasize the versatility of oxide electronics research we choose the first of these with a perspective on basic research while the second example emphasizes the device potential of oxide films and heterostructures.(1)Structures uniting ferroelectric and magnetic long-range order. It is our goal to obtain and control pronounced cross-coupling effects between the magnetic and dielectric properties of heterostructure geometries even up into the optical range. (2)Oxide films with strain-dependent structure-charge transport correlation. We anticipate applications such as resistive random access memories and micro-solid oxide fuel cells integrated on Si-chips or flexible polymer substrates.The core of the proposal is the acquisition of the equipment for high-energy pulsed laser deposition (PLD). The PLD lab will be the only one of its kind at the ETH Zurich. It will allow both PIs, who are newly appointed faculty members, to enter new and interdisciplinary research fields by defining joint projects pushing synergy effects between their research teams: Based on his background in bulk multiferroics and light-matter interaction in oxides Manfred Fiebig will expand his activities into the field of functional magnetoelectric (ME) and device-oriented aspects of oxide heterostructures grown under his supervision. Jennifer Rupp has a strong background in solid-state electrochemistry, thin film processing, structure-charge transport engineering, and classic Si microfabrication. She will add microstructuring of ME oxides to her activities. In particular, the PIs define the following four research projects as the first ones that will be based on the new PLD laboratory. (1)Thin magnetoelectric films with coupled and decoupled multiferroic order(2)Trilayer superstructures with passive and active magnetoelectric modulation (3)Interface engineering for resistive random access memories (4)Heterostructure electrolytes
