Fermi Arcs in an Antiferromagnet detected at BESSY II

Researchers have analyzed samples of NdBi crystals which display interesting magnetic properties. In their experiments including measurements at BESSY II they could find evidence for so called Fermi arcs in the antiferromagnetic state of the sample at low temperatures. This observation is not yet explained by existing theoretical ideas and opens up exciting possibilities to make use of these kind of materials for innovative information technologies based on the electron spin rather than the charge.

Don’t underestimate undulating graphene

A theory suggests putting graphene on an undulating surface stresses it enough to create a minute electromagnetic field. The phenomenon could be useful for creating 2D electron optics or valleytronics devices.

Design tweak helps prevent malfunction in yarns designed to store energy

Findings in a recent study could advance the development of 'smart textiles' that would capture energy from the wearer's movements.

Making memory serve correctly: Fixing an inherent problem in next-generation magnetic RAM

SOT-RAM, a promising type of next-generation magnetic memory, could pave the way to ultra-low-power electronics. However, scientists have identified a source of disturbance during the read operation in SOT-RAMs that compromises their reliability. Fortunately, they also found a method to greatly reduce this disturbance by slightly modifying the SOT-RAM structure. Their findings will help make this type of memory faster and more reliable, helping its commercialization for sustainable IoT applications.

Scientists devise new technique to increase chip yield from semiconductor wafer

Scientists have developed a technique to create a highly uniform and scalable semiconductor wafer, paving the way to higher chip yield and more cost-efficient semiconductors.

New strategy for designing thermoelectric materials

Scientists have developed a new approach to the design of thermoelectric materials by constructing a database of electronic structure parameters correlated with materials' thermoelectric conversion properties and by a comprehensive analysis of the database. This approach can be used to develop higher performance thermoelectric materials.

Tiny battery-free devices float in the wind like dandelion seeds

Inspired by how dandelions use the wind to distribute their seeds, a team has developed a tiny sensor-carrying device that can be blown by the wind as it tumbles toward the ground.
