Using data from the British neutron source ISIS from the year 2000, research teams have now demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material. A team from HZB led by Prof. Bella Lake was also involved in the analysis.
- Perowskit/Silizium-Tandemsolarzellen auf dem Weg vom Labor in die ProduktionKOALA/KOALA+ - Die am Helmholtz Zentrum Berlin (HZB) errichtete Clusteranlage ermöglicht Wafer mit Perowskit/Silizium-Tandemsolarzellen im Vakuum herzustellen; ausreichend groß, um eine industrielle Produktion abzubilden. Diese weltweit einzigartige Anlage trägt dazu bei, neue industrienahe Prozesse, Materialien und Solarzellen zu entwickeln.
- Atomic displacements in High-Entropy Alloys examinedHigh-entropy alloys of 3d metals have intriguing properties that are interesting for applications in the energy sector. An international team at BESSY II has now investigated the local order on an atomic scale in a so-called high-entropy Cantor alloy of chromium, manganese, iron, cobalt and nickel. The results from combined spectroscopic studies and statistical simulations expand the understanding of this group of materials.
