Theorists and experimentalists working together at Cornell may have found the answer to a major challenge in condensed matter physics: identifying the smoking gun of why “unconventional” superconductivity occurs, they report in Nature Physics, published online Dec. 22.
Associate professor of physics Eun-Ah Kim led the way, joining forces with experimentalist J.C. Seamus Davis, the J.G. White Distinguished Professor of Physical Sciences in the College of Arts and Sciences. They have isolated a “fingerprint” that identifies specific fluctuations in electrons that force them into pairs, causing their host material, in this case, a high-temperature superconductor called lithium iron arsenic, to make way for free-flowing, resistance-free electron pairs.

Ithaca, NY - The Cornell Center for Materials Research JumpStart program, funded by Empire State Development’s Division of Science, Technology and Innovation (NYSTAR), is designed to assist New York State small businesses develop and improve their products through university collaborations; the ultimate goal is revenue growth and job creation. JumpStart projects receive up to $5,000 in matching funds for project costs that include faculty and research staff, facilities, services, supplies, and materials. Since its inception, 63 companies have benefited from this program. During the upcoming semester, five companies have been awarded funding and will participate in the following collaborations:
 

Metglas, Inc., the world's leading producer of Amorphous Metal Foil (www.metglas.com) is pleased to welcome the first Ryusuke Hasegawa Graduate Fellow: David Kemmenoe, Ph.D. student in Mechanical  and Aerospace Engineering.  David will be doing his Ph.D. research on the "Nanoscale Material Structure Influence on Mechanical Properties in Thin Metallic Glasses" with Ph.D. advisor Professor Shefford Baker, Materials Science and Engineering.

JumpStart projects receive up to $5,000 in matching funds for project costs that include faculty and research staff, facilities, services, supplies, and materials. Since its inception, 59 companies have benefited from this program. During the upcoming semester, three companies have been awarded funding and will participate in the following collaborations:
 
Incodema3D Inc., Ithaca, NY will collaborate with Professor Shefford Baker, Materials Science and Engineering to characterize the physical properties of several metallic materials made into test specimens by an additive 3D manufacturing process.

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.

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
