CEM Facilities Utilized for Research Published in Science Advances

Last week, IRG-2 member Jeanie Lau’s paper “Correlated insulating and superconducting states in twisted bilayer graphene below the magic angle” was published in Science Advances.

Lau, professor of physics at Ohio State and lead author on the paper, and her team studied the “magic angle” that makes graphene layers become a superconductor, meaning they are able to conduct electricity without resistance, suffering no loss of energy. The team found that graphene layers remained supconductive over a smaller angle than previously thought possible, opening up more possibilities for their use in real world applications.

The NanoSystems Laboratory, a CEM-supported research facility at Ohio State, was utilized for device fabrication necessary to perform experiments for this study.

Lau and other Ohio State researchers collaborated with scientists at the University of Texas- Dallas and the National Institute for Materials Science in Japan. More information about this research and the team can be found on Ohio State’s news website. You can read the paper on the Science Advances website.


Ohio State Recognized as Midwestern Hub of Next-Gen Magnetic Resonance Research

Ohio State: Midwestern Hub of Next-Gen Magnetic Resonance Research | Electrical and Computer Engineering

September 13, 2016


Magnetic resonance is one of the most important phenomena in materials and medical research. Its broad range of applications has revolutionized modern technologies, from wireless communication to radar, while saving millions of lives in the medical realms through the early detection of disease.

A team of physicists and engineers at The Ohio State University has now won a $1.071 million award from the National Science Foundation’s Major Research Instrumentation program (NSF-MRI) to help advance the study of magnetic resonance technology at the nanoscale level. Over the next three years, they will work to develop and build new equipment capable of discovering novel magnetic resonance phenomena at a very high frequency range up to 330 Ghz. The Institute for Materials Research (IMR) at Ohio State coordinated the group effort that ultimately led to the winning NSF-MRI award.

Department of Physics Professor and IMR Associate Director Fengyuan Yang, Principal Investigator (PI) on the project, said the technology they are developing could make Ohio State a center for high-frequency magnetic resonance research across the Midwest. Once constructed, the new instrument will be located inside the university’s NanoSystems Laboratory, a facility open to all academic and industrial users.

“This will be the first magnetic resonance spectrometer within this frequency range at a shared user facility in the Midwest,” Yang said, “and it will significantly strengthen and expand the investigation of novel fundamental phenomena and the development of paradigm-changing technologies for researchers at Ohio State and from across the region.”

The NSF-MRI project team includes Yang, with co-investigators P. Chris Hammel, professor of Physics; John Volakis, professor of Electrical and Computer Engineering (ECE); Joseph Heremans, professor of Mechanical and Aerospace Engineering and Physics; Rolando Valdes Aguilar, assistant professor of Physics; Zeke Johnston-Halperin, associate professor of Physics; and Denis Pelekhov, director of the NanoSystems Laboratory.

MRFN Funding Available for NSL Users

Funding Available to use NSL for Eligible Applicants

The Center for Emergent Materials is a member of the Materials Research Facilities Network, a nationwide partnership of the Shared Experimental Facilities (SEFs) supported mrfn_mrsec_transparent_logoby the National Science Foundation’s Material Research Science and Engineering Centers (MRSECs). CEM participates in the MRFN through support of NanoSystems Laboratory (NSL).

Funding support is available to cover NSL user fees and/or travel expenses to Ohio State for eligible applicants. Ideal applicants will be collaborators or come from local institutions that otherwise would not have access to comparable research instrumentation. To apply, submit a one to two page description of work and broader impacts to cem@osu.edu.

NSL Acquires Origin Pro 9.1 Licenses for User Purchase

NanoSystems Laboratory (NSL)  has acquired a site license for Origin Pro 9.1. It is a one year subscription for 100 concurrent instances of the program. Origin Pro can be installed on any computer, OSU owned or private that is connected to the OSU network, as long as the user is the current OSU student, staff or faculty. Once the program has been installed in the computer, users will need to acquire the license key for each session of software use. The price of the license for one computer is $87.50/year, which will be prorated to reflect purchases made later in the year. Purchases can be made via eRequest to NanoSystems Laboratory for the desired number of licenses, and should contain the list of MAC addresses of the computers on which the software will be installed. Once the eRequest is approved, NSL will issue instructions on how to access the license server. Installation of the program can be done via installation media that can be borrowed from NSL service desk.

Contact NSL program assistant Asnika Bajracharya (bajracharya.5@osu.edu) with any questions.
