Like the perfect sandwich, a perfectly engineered thin film for electronics requires not only the right ingredients, but also just the right thickness of each ingredient in the desired order, down to individual layers of atoms.

Cornell researchers have discovered that sometimes, layer-by-layer atomic assembly – a powerful technology capable of making new materials for electronics – requires some unconventional “sandwich making” techniques.

The team, led by thin-films expert Darrell Schlom, the Herbert Fisk Johnson Professor of Industrial Chemistry in the Department of Materials Science and Engineering, describes the trick of growing perfect films of oxides called Ruddlesden-Poppers in Nature Communications Aug. 4. 

 

Scientists are closing in on the secret recipe for high-temperature superconductors. The secret ingredients are still unknown, but new research at Cornell and Brookhaven National Laboratory has revealed a little more about how they are mixed. Three previously observed events associated with the emergence of superconductivity turn out to occur at the same time.

Two out of three of these events – the disappearance of a “striped” arrangement of electrons and a broken symmetry in the arrangement of electrons around atoms – had already been observed to occur together. This inspired researchers to compare those events with the distribution of energy levels of the electrons in the material that are free to conduct electricity. They report their results in the May 8 issue of the journal Science.

 

On May 20, the CCMR held its 2014 symposium. It focused on Spin Control and commercial applications such as the next generation of MRAM. Dr. Albert Fert, 2007 Nobel Prize in Physics, gave the 2014 Sproull Lecture. The symposium was a day-long event, which gathered 100 off-campus guests and Cornell faculty and students. The off-campus attendees selected for best poster:  “THz Generation in Antiferromagnetic NiO” by Jared Strait, Parinita Nene, and Prof. Farhan Rana.

Thank you to the Organizing Committee and the CCMR staff for putting the event together.

We are pleased to announce that Dr. Jonathan Shu has filled the role of Associate Director for the Cornell Center for Materials Research. Jon brings a wealth of scientific and management expertise to this position.
 

CornellChronicle By Bill Steele - Ashim Datta, professor of biological and environmental engineering; Melissa Hines, professor of chemistry and chemical biology; and David Sherwyn, the John and Melissa Ceriale Professor of Hospitality Human Resources and academic director of the Cornell Institute for Hospitality Labor and Employment Relations, have received Stephen H. Weiss Presidential Fellowships in recognition of their inspiring teaching of undergraduate students, President David Skorton announced at the Cornell Board of Trustees meeting in January.

“It is my pleasure to announce the new Weiss fellows, whose nominations by their students and colleagues attest to their extraordinary teaching and mentoring,” said Skorton. “They have our deep appreciation, admiration and gratitude.”

Research

The CCMR currently supports three Interdisciplinary Research Groups (IRGs) and a number of smaller 'seed' research groups through an NSF MRSEC grant and Cornell University support. Each group brings researchers from a variety of different departments together to work on an outstanding interdisciplinary problem in materials research and development. Read more
