Grubišić-Čabo, along with collaborators from Poland, Germany, France, and Italy, studied sheets of a 2D material called tungsten disulfide. Theoretical predictions suggested that when two sheets, or a bilayer, are stacked at a precise angle of 4.4 degrees, the electrons within the material should exhibit collective behavior.
“And when they are so closely connected, their collective behavior can create new, fascinating effects,” explains Giovanna Feraco, first author of the study
