2D materials with 'twist' show unexpected electronic behavior that defy theoretical predictions

In the search for new materials that can enable more efficient electronics, scientists are exploring so-called 2D materials. These are sheets of just one atom thick, that may have all kinds of interesting electronic properties. If two sheets are placed on top of each other at specific angles, this may lead to new properties such as superconductivity. University of Groningen materials scientist Antonija Grubišić-Čabo and her colleagues studied such a "twisted" material and discovered that it defied theoretical predictions.
