Novel method enhances size-controlled production of luminescent quantum dots

🌟 Congratulations to EPiQS Experimental Investigators Amir Yacoby and Pablo Jarillo-Herrero whose recent breakthrough in the field of "twistronics" has simplified the manipulation of 2D materials, a key aspect of the rapidly advancing technology. Twistronics revolves around adjusting the angle between two stacked layers of ultra-thin materials like graphene, transforming their electrical properties, which can lead to novel behaviors like superconductivity. Their newly developed device makes it easier to control these "twist angles" with high precision, streamlining the process of experimenting with various configurations. This could have significant implications for the development of next-gen electronics, quantum computing, and materials science. By better understanding the interaction between the stacked layers, researchers can explore new ways to control electronic behavior at the nanoscale.

The Future of Quantum Materials: Atomic Robotic Probes for Precise Fabrication Open-shell magnetic nanographenes hold immense potential for next-gen electronics and quantum computing. However, achieving precise atomic-level control during synthesis has been a hurdle. A new study in Nature Synthesis proposes a revolutionary solution: chemist-controlled robotic probes for single-molecule manipulation! This tech offers real-time, autonomous reactions with incredible bond selectivity, paving the way for highly controlled fabrication of quantum materials. This is a game-changer for the future of quantum technology. #Science #Nanotechnology #QuantumComputing https://lnkd.in/g-4ts8Ps

Spintronics leaping ahead with yet another magnetic vortices called ‘merons’ that are rarer cousins of skyrmions who came ashore recently as a possible next generation computing device platform from Singapore. Both are collective topological structures formed of numerous individual spins. Merons have to date only been observed in natural antiferromagnets, where they are difficult to both analyze and manipulate. These researchers have been the first to demonstrate the presence of merons in synthetic antiferromagnets and thus in materials that can be produced using standard deposition techniques. “We were able to devise a novel habitat for what is a new and very ‘shy’ species,” said Dr. Robert Frömter, a physicist at JGU. The research achievement involves designing synthetic antiferromagnets in such a way that merons are formed in them as well as the detection of the merons themselves. In order to put together the corresponding materials made of multiple layers, the researchers undertook extensive simulations and conducted analytical calculations of spin structures. The goal was to determine the optimal thickness of each layer and the suitable material to facilitate the hosting of merons and to understand the criteria for their stability. In tandem with theoretical work, the team pursued experiments to address these challenges. With the aid of magnetic force microscopy in conjunction with the less familiar scanning electron microscopy with polarization analysis, they successfully identified merons in their synthetic antiferromagnets. They have thus managed to make a step forward towards the potential application of merons. #climatechange #aiml #spintronics #hpc #largescalenonvolatilememory

Quantum precision: A new kind of resistor: Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect. @Poseidon-US #ScienceDaily #Technology

Materials found in the third and fifth groups of the periodic table (III-V materials) are used in the most efficient solar cells, brightest LEDs, most powerful semiconductor lasers, and fastest electronic devices. They would potentially make great quantum dots, but, with few exceptions, it was impossible to use them to grow nanocrystals in solution. The temperatures required to make these materials were too high for any known organic solvent. https://lnkd.in/g3kMnWkT
