On the Hunt for Ultra-Thin Materials Using Data Mining

Study identifies extensive set of novel 2D materials


Two-dimensional (2D) materials possess extraordinary properties. They usually consist of atomic layers that are only a few nanometers thick and are particularly good at conducting heat and electricity, for instance. To the astonishment of many scientists, it recently became known that 2D ...

Speeding through nanowire

Nanowires under tension create the basis for ultrafast transistors


Smaller chips, faster computers, less energy consumption. Novel concepts based on semiconductor nanowires are expected to make transistors in microelectronic circuits better and more efficient. Electron mobility plays a key role in this: The faster electrons can accelerate in these tiny wires, ...

Precise sample alignment under extreme conditions

Prototype already in use


The exact angular alignment of sample materials for the determination of their physical properties under extreme conditions is often difficult. Engineer Stefan Findeisen and physicist Dr. Hannes Kühne from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed the "Rotax", a filigree ...

When batteries become foam

New concept for improved battery recycling


Efficiently recycling batteries and reintegrating the recovered materials into production is still an apparently unsolvable problem for industry. That's why researchers around the world are looking for new approaches. One of them is Anna Vanderbruggen. The PhD student at the Helmholtz Institute ...

International team improves efficiency of liquid metal batteries

Improved electrolyte formulation increase the power efficiency to nearly 100 percent


Climate protection means increasingly turning to renewable energies. But in order to store the energy produced by solar, wind and other regenerative processes, sophisticated systems are required. Today’s storage options are still too expensive and hardly or even impossible to recycle. Scientists ...

Pancake strategy for the win

Special heat treatment improves novel magnetic material


Skyrmions – tiny magnetic vortices – are considered promising candidates for tomorrow’s information memory devices which may be able to achieve enormous data storage and processing capacities. A research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a method to grow a ...

Bipolar doping

New approach facilitates the control of reversible conductivity in semiconductors


The semiconductor gallium oxide is thought to be a promising candidate for potential use in power electronics. So far, however, a number of obstacles have stood in its path, especially how to specifically influence the material’s electrical conductivity. In a study published in the journal ...

Scientists create three-dimensional nanostructures using ion beams

For tomorrow’s computers


Effects at the interface between magnetic and non-magnetic layers have been exploited for data storage for three decades. This has led to a steady increase in hard drive storage capacity and is one reason why researchers see potential for ushering data processing into a new era. One way these ...

Dynamic, yet inertial – and definitely futuristic

Researchers conduct experiments to demonstrate inertial motion in magnetic materials: Groundwork for ultra-fast data storage


In the journal Nature Physics, an international team of scientists from Germany, Italy, Sweden, and France report on their experimental observation of an inertial effect of electron spins in magnetic materials, which had previously been predicted, but difficult to demonstrate. The results are the ...
