EMA 2013 expands scope while staying focused

By Eileen De Guire / January 24, 2013

More than 250 people are here at the 2013 Electronic Materials and Applications currently underway in Orlando, Fla. It still feels like a small, intimate meeting even though organizers expanded the scope of the meeting with several new symposia and a conscious reach into the broader electronics community, while staying true to the meeting’s mission.…

Perovskite-based tunable superlens developed

By Eileen De Guire / March 30, 2011

Experimental setup shows an IR free-electron laser light source and perovskite superlens consisting of BiFeO3 and strontium titanate SrTiO3 layers. Imaged objects are strontium ruthenate patterns (orange) on a SrTiO3 substrate. The near-field probe is shown in blue and the evanescent waves in red. Credit: Kehr, et. al. The DOE’s Lawrence Berkeley National Lab and Ramamoorthy Ramesh…

New ‘domains’ for nano electronics

By / February 9, 2009

Researchers say that logic and memory functions of future electronic devices could shrink an order of magnitude (one or two nanometers, instead of tens of nanometers) if they can control domain walls, the transition zones in a material that separate regions of different magnetic, electric or other properties. And, by “control,” the researchers remarkably mean…
