In these resonant states, electrons bounce back and forth between the two atomic planes in the 2D interface at the same frequency. By characterizing these states, they found that twisting one of the graphene layers by 30 degrees relative to the other, instead of stacking the layers directly on top of each other, shifts the resonance to a lower energy. From this result, just published in Physical Review Letters, they deduced that the distance between the two layers increased significantly in the twisted configuration, compared to the stacked one. When this distance changes, so do the interlayer interactions, influencing how electrons move in the bilayer system. An understanding of this electron motion could inform the design of future quantum technologies for more powerful computing and more secure communication.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-08-layered-graphene-unique-quantum-confinement.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Layered graphene with a twist displays unique quantum confinement in 2D<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists studying two different configurations of bilayer graphene\u2014the two-dimensional (2D), atom-thin form of carbon\u2014have detected electronic and optical interlayer resonances.
