Even on its own, this so-called \u201cwonder material\u201d boasts many exceptional properties, including high electrical conductivity as charge carriers (electrons and holes) zoom through the carbon lattice at very high speeds.<\/p>\n<p>In 2018, researchers led by <a href=\"http:\/\/jarilloherrero.mit.edu\/\" target=\"_blank\" rel=\"noopener noreferrer\">Pablo Jarillo-Herrero<\/a> of MIT found that when two such sheets are placed on top of each other with a small angle misalignment, things become even more fascinating. In this twisted bilayer configuration, the sheets form a structure known as a moir\u00e9 superlattice, and when the twist angle between them reaches the (theoretically predicted) \u201cmagic angle\u201d of 1.08\u00b0, the material begins to show properties such as superconductivity at low temperatures \u2013 that is, it conducts electricity without any resistance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Superconductivity can be switched on and off in \u201cmagic-angle\u201d graphene using a short electrical pulse, according to new work by researchers at Massachusetts Institute of Technology (MIT).
