CEM Researchers help ‘stretch’ a lackluster material into a possible electronics revolution
Ho-hum to high performance: Researchers ‘stretch’ a lackluster material into a possible electronics revolution
ITHACA, N.Y. — It’s the Clark Kent of oxide compounds, europium titanate and – on its own – it is pretty boring. But slice it nanometers thin and chemically stretch it, europium titanate takes on super hero-like properties that could revolutionize electronics, according to new Cornell research. (Nature, Aug. 19, 2010.)
Publishing in the journal Nature Aug. 19, researchers report that thin films of europium titanate become both ferroelectric (electrically polarized) and ferromagnetic (exhibiting a permanent magnetic field) when stretched across a substrate of dysprosium scandate, another type of oxide. Up until now, the best simultaneously ferroelectric, ferromagnetic material to date pales in comparison by a factor of 1,000.
Simultaneous ferroelectricity and ferromagnetism is rare in nature and coveted by electronics visionaries. A material with this magical combination could form the basis for low-power, highly sensitive magnetic memory, magnetic sensors or highly tunable microwave devices. Continue reading

Len Brillson, CEM Faculty Member and IRG-2 Co-Leader, Chosen as NSF American Competitiveness and Innovation (ACI) Fellow for 2010
Prof. Len Brillson, CEM Faculty member and IRG-2 co-Leader, has been chosen as a American Competitiveness and Innovation (ACI) Fellow for 2010 by the NSF Division of Materials Research. As part of the ACI Fellowship, Prof. Brillson will receive up to $360,000 in research funding from NSF. The ACI Fellowship citation states: “For establishing the optical signature of a leading defect in ZnO, opening the way to monitor and study processes that promote p-type conductivity, a major current objective in semiconductor optoelectronics. He is also recognized for his outstanding efforts in student mentoring and broadening participation of underrepresented groups in science.”
