A study led by University of Minnesota physics researchers has discovered that a unique superconducting metal is more resilient when used as a very thin layer.
Examining an iron chalcogenide high-temperature superconductor, an international team of researchers has found that just before the material fully enters the nematic state, electronic nematicity first appears in nanoscale patches on its surface. In addition, minute stretching of the material, or strain, can induce local nematicity, which in turn suppresses superconductivity, according to a report in Nature Physics.
Magnetic-spin interactions that allow spin-manipulation by electrical control allow potential applications in energy-efficient spintronic devices. A Chinese-Australia collaboration published today describes for the first time the induction of such interactions in a layered material tantalum-sulfide by addition of iron atoms, and tuning by insertion of protons.
Research led by the University of Kent and the STFC Rutherford Appleton Laboratory has resulted in the discovery of a new rare topological superconductor, LaPt3P. This discovery may be of huge importance to the future operations of quantum computers.
Researchers have discovered a new and more efficient computing method for pairing the reliability of a classical computer with the strength of a quantum system.
In research published today in Nature Communications, engineers from Rensselaer Polytechnic Institute demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices' properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward developing quantum emitters needed for future quantum simulation and computing.
By shining laser light on semiconducting moiré superlattices formed by stacking two atomically thin materials -- monolayer tungsten diselenide (WSe2) and monolayer molybdenum diselenide (MoSe2) -- a team led by researchers at the University of California, Riverside, and Academia Sinica in Taiwan found a new class of electronic excited states called "moiré trions." The study opens up new opportunities to develop trion-based quantum optical emitters and offers new approaches to explore moiré physics.
Recently, a research team led by Professor ZHAO Bangchuan from the Institute of Solid Materials of the Hefei Institutes of Physical Science (HFIPS) synthesized 3D porous honeycomb-like CoN-Ni3N/N-C nanosheets and vanadium nitride (VN) nanobelt arrays via in-situ growth method, respectively, and constructed a high-energy-density flexible supercapacitor device. The result has been published in Advanced Functional Materials.
The movement of electrons can have a significantly greater influence on spintronic effects than previously assumed. This discovery was made by an international team of researchers led by physicists from the Martin Luther University Halle-Wittenberg (MLU). Until now, a calculation of these effects took, above all, the spin of electrons into consideration. The study was published in the journal "Physical Review Research" and offers a new approach in developing spintronic components.
South Korea's Ulsan National Institute of Science and Technology (UNIST) has succeeded in investigating and controlling the physical properties of naturally-formed nanoscale wrinkles in 2D semiconductors.
