Physicists create tunable superconductivity in twisted graphene "nanosandwich"

Boston MA (SPX) Feb 02, 2021
When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy. This “magic-angle” transformation in bilayer graphene was observed for the first time in 2018 in the group of Pablo Jarillo-Herrero, the Cecil and Ida Green Profes Source: NanoDaily.com Physicists create tunable superconductivity in twisted graphene "nanosandwich"
