NSF Funds NV Quantum Sensing Capabilities for NCMN Attocube System

Acquisition of optical access in a cryogenic scanning probe microscope for quantum sensing capabilities." This instrument will leverage the existing scanning probe microscopy capabilities we have at NCMN and add the first commercial quantum sensing device to the set of characterization facilities at NCMN. There are only a few instruments of this kind available throughout the country. Christian Binek is the PI, and Xia Hong, Abdelghani Laraoui, and Xiaoshan Xu are Co-PI's.
We can’t wait to set the system up and see it producing scientific results. (8/18/22)

Team achieves ‘significant breakthrough’ in data-encoding material

Bucking years of conventional wisdom, Husker researchers have shown that hafniumm oxide's most technologically appealing property can emerge from unexpected conditions. In a new Nature Materials study, a team led by Nebraska’s Xiaoshan Xu, Evgeny Tsymbal and Alexei Gruverman has demonstrated that growing a higher-quality, larger-grained crystal of hafnium oxide can actually generate higher polarization and potentially more reliable ferroelectricity. The quality of the crystal, meanwhile, is offering sharper insights into how and why that ferroelectricity occurs. (7/11/22)

Researchers from the University of Nebraska-Lincoln and the University of California, Berkeley, have developed a new photonic device that could get scientists closer to the “holy grail” of finding the global minimum of mathematical formulations at room temperature. Finding that elusive mathematical value would be a major advancement in opening new options for simulations involving quantum materials.

Remembering the life and work of David Sellmyer

Founding director of the Nebraska Center for Materials and Nanoscience, David J. Sellmyer, 83, died at home surrounded by his family on March 25. Sellmyer was the driving force behind the creation of NCMN, the Voelte-Keegan Nanoscience Research building, and the Nebraska Nanoscale Facility. Dan Claes, current department chair and professor of physics and astronomy said of Sellmyer's leadership, "I don’t believe there’s anyway we could overstate the impact Dave has had on the department, university and specifically our materials science program. It’s a legacy that will be with us this forever.”

Condolences can be left on the Wyuka website, and a recording of the funeral service is available on YouTube. (4/5/22)

Bao's CAREER Award supports work to make quantum simulators function at room temperature

Quantum simulators are key tools in the study of quantum systems, but their use is limited because they must operate with bulky ultra-low-temperature vacuum systems beyond the capacity of many research labs. With a five-year, $756,713 grant from the National Science Foundation’s Faculty Early Career Development Program, Wei Bao hopes to find a way to make those simulators function at room temperature; this would greatly expand the scope and accessibility of work with quantum simulators.

Evgeny Tsymbal.
Tsymbal team's data-decoding approach could lead to faster, smaller digital tech

Evgeny Tsymbal and colleagues have published a new study showing that spin-independent conductance in compensated antiferromagnets and normal metals can be efficiently exploited in spintronics. The team identified ruthenium oxide as just such an antiferromagnet, as well as titanium dioxide as the barrier through which electrons can tunnel. Critically, the atoms of the two respective oxides form the same crystalline structure, resulting in a seamless match that allows electrons to maintain their momentum — and their momentum-dependent spin — as they move between the materials. This research was supported, in part, from the National Science Foundation's $20 million grant facilitating Nebraska's EPSCoR-EQUATE project. (1/6/22)

Shield and team look to boost heat transfer of copper

Jeff Shield and colleagues have been investigating how to improve the heat transfer of copper used in pool boiling. In a new study, the team increased the surface area of copper by firing 4-picosecond-long laser pulses at it. However, this also coated the surface with oxides that curbed the otherwise improved heat transfer. So the team tried cleaning the surface with different acids, and found that citric acid worked best, but only when the number of laser pulses remained below a certain threshold. (11/15/21)

Xia Hong and colleagues (including Evgeny Tsymbal and Stephen Ducharme) have developed a new technique allowing them to study and more precisely measure the anisotropy of a promising semiconductor - rhenium disulfide. By layering a ferroelectric polymer atop the rhenium disulfide, then flipping the polarization of a narrow sliver within the polymer, the team discovered that rhenium disulfide’s conductivity greatly depends on the orientation of the path itself. They also found the anisotropy was largest when measuring it in rhenium disulfide that was four atomic layers thick. (9/22/21)

Yongfeng Lu and colleagues have developed a low-cost, scalable method of protecting carbon fibers from oxidation when exposed to extreme temperatures.

The coated carbon fibers remained undamaged when exposed to 2,200 degrees Fahrenheit and extreme environmental conditions simulated with an oxyacetylene flame. Bai Cui is also involved in this research. (7/26/21)

Tim Gay and colleagues have discovered the answer to a football physics question that stumped him for years - when a quarterback throws a deep, well-thrown pass, why does the football point up when thrown and then down when about to be caught? The answer lay in the concept of gyroscopic stabilization. The team knew that a well-thrown football, like the high-RPM gyroscope, possesses plenty of angular momentum. But with the aid of math and computer simulations, they came to a vital conclusion: The football can adopt a precession, too. (10/5/20)

Research led by David Sellmyer and Balamurugan Balasubramanian has resulted in the formation of skyrmions that are seemingly the smallest possible size at only 13 nanometers wide. This new finding could improve digital memory, including better energy efficiency, faster data processing speeds, and longer lifespans for hard drives. (7/12/18)

Researchers record “molecular movie” of photochemical reaction

Martin Centurion and colleagues, including researchers from Stanford University and Europe, have been able to precisely capture how the atomic nuclei and chemical bonds of a five-atom molecule responded when struck by a laser. The study marks the culmination of a years-long effort to advance the quality of “molecular movies” from that of a rudimentary stop-motion animation to a high-definition motion picture. (7/9/18)

Yang earns grant for converting feathers to fiber

Yiqi Yang and his team were awarded a $211,885 two-year pilot-scale production grant to continue their work on developing a product made from certain fibers found in feathers and wool. Textiles made with these fibers have increased performance properties, including moisture transmission, thermal insulation, soft hand and luster. (6/25/18)

David Sellmyer.
Sellmyer Honored at MRS Meeting

The Spring MRS Meeting in Phoenix hosted a five-day Symposium “Nanoscale Magnetic Structures and Materials,” which was organized by friends and colleagues of David Sellmyer to celebrate his many achievements and contributions to the field. Some 30 outstanding invited talks were presented by speakers including Stuart Parkin (Halle), Claudia Felser (Dresden), Ivan Schuller (UCSD), Michael Coey (Dublin), Sara Majetich (CMU), Shouheng Sun (Brown), J.P. Wang (MN), B. Koopmans (Eindhoven), Y. Hou (Beijing), Arun Gupta (Alabama), Axel Hoffmann (ANL), and others. Current and former Nebraska colleagues and speakers included: Ralph Skomski, Jeff Shield, George Hadjipanayis, Toshi Matsui, Damien LeRoy, Yunlong Jin, and co-organizers J. Ping Liu and Hao Zeng. A banquet on April 3 featured excellent food and several roasts with good-natured ridicule. (5/18/18)

Tsymbal and colleagues observe long-sought phenomenon

Two UNL researchers were part of an international team that ended a 15-year quest to observe a phenomenon that could help power a future generation of (smaller) electronics. In 2004, researchers observed a gas of electrons coursing two-dimensionally through a nano-sandwich made from oxides. This suggested that electric currents could be confined to smaller spaces, allowing electronic components to shrink in size. However the negatively charged electron also leaves behind a positively charged “hole” when ejecting from its orbit around an atom. The goal of researchers was to create and observe a 2-D hole gas that likewise acts as a source of electric current. (3/7/18)
