In 2018, MIT physicist Pablo Jarillo-Herrero discovered an arrangement of this material that was a major development in the field of twistronics. The labels K and K-prime denote six points where this material’s valence and conduction bands meet, (10[1])the discovery of which was the first (10[1])experimental evidence for Dirac cones. (10[1])Two pieces of this material can exhibit superconductivity if overlaid at a “magic angle” of 1.1 degrees. This popular nanoribbon material was traditionally produced through epitaxial growth before the discovery of a method by Andre Geim and Konstantin Novoselov; that exfoliation process (10[1])isolates this material using Scotch (10[1])tape. (10[1])For 10 points, (10[1]-5[1])name this extremely conductive two-dimensional allotrope of carbon. ■END■ (10[1]0[1])
