Scientists recently discovered novel quantum materials whose charge carriers exhibit ‘topological’ features that result in the charge’s transport not being affected by continuous transformations. Because of this “protection,” topological materials often show peculiar quantum states on their surfaces and edges. This study observed superconducting edge currents for what the researchers believe is the first time.

Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating properties determined by quantum mechanics. Researchers at the University of Vienna in collaboration with the Universities of Tübingen, Antwerp and CY Cergy Paris, together with Danubia NanoTech, have produced a new 2D material made of copper and iodine atoms sandwiched between two graphene sheets. The results were published in the journal Advanced Materials.

As the name implies, crystallography requires crystals – specifically, purified samples of the molecule of interest, coaxed into a crystal form. But most molecules form powders composed of jumbled granules, not picture-ready crystals. A new computer algorithm, combined with a state-of-the-art laser, can adapt X-ray crystallography for the many not-so-neat-and-tidy compounds that scientists seek to study.
