High-temperature superconductors have the potential to transform everything from electricity transmission and power generation to transportation. The materials, in which electron pairs travel without friction—meaning no energy is lost as they move—could dramatically improve the energy efficiency of electrical systems. Understanding how electrons move through these complex materials could ultimately help researchers design superconductors that…

Since the 2003 discovery of the single-atom-thick carbon material known as graphene, there has been significant interest in other types of 2-D materials as well. These materials could be stacked together like Lego bricks to form a range of devices with different functions, including operating as semiconductors. In this way, they could be used to…
