Computational quest for 2D materials

Two-dimensional materials with a unique set of physical and chemical properties and the tangible potential for various electronic and optoelectronic applications have generated a substantial amount of experimental studies. Yet, all these works are based on only a few dozens of practically exfoliable materials. Using high-throughput calculations, N. Mounet and co-workers have now succeeded in identifying 1,825 potentially exfoliable two-dimensional materials and predicted some of their essential physical properties. The cover is an artist's depiction of diverse two-dimensional materials. The different colours represent different atoms in each flake. Some of the flakes are atomically thin and some consists of a few atomic layers.]

    Single magnetic skyrmions are electrically detected in magnetic multilayers at room temperature, and their main contribution to the signal, which is enhanced for tracks approaching the size of the skyrmions, comes from the anomalous—rather than topological—Hall effect.
