New techniques for aligning nanocrystals enhance solar-cell efficiency and LED performancesource:RIKENIn a study that unlocks exciting possibilities for solar cells and light-emitting diodes (LEDs) based on materials known as perovskites, RIKEN researchers have refined techniques for controlling the optical and electronic properties of perovskite nanocrystals.The high tunability of all-inorganic nanocrystals made from perovskite materials with the chemical formula CsPbX3 (where X is a halide such as chlorine, bromine or iodine) make them attractive for use in various applications, including bi...

source:Phys.orgA team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold under ambient pressure. In their study published in Nature, the researchers synthesized thin films of bilayer nickelate (La₂.₈₅Pr₀.₁₅Ni₂O₇) and found one that behaved as a high-temperature superconductor.The -233°C threshold (40 K), often associated with the McMillan limit, marks a boundary beyond which conventional superconductivity theories become less predictive.Scientist...

source:Helmholtz Association of German Research CentresCadmium selenide nanoplatelets provide a promising foundation for the development of innovative electronic materials. Researchers around the world have taken a particular interest in these tiny platelets, which are only a few atoms thick, as they offer extraordinary optical and other properties.A team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Dresden, and the Leibniz Institute for Solid State and Materials Research Dresden (IFW) has taken an important step toward the systematic production of such nanoplatelets. The researche...
