MIT physicists found a way to switch superconductivity on and off in magic-angle graphene. The discovery could lead to ultrafast superconducting transistors for “neuromorphic” electronics that operate similarly to the rapid on/off firing of neurons in the human brain.
Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics at MIT, delivered the 2022 Mildred S. Dresselhaus lecture on magic-angle graphene and the rise of moiré quantum matter.
MIT physicsts identified new multilayered configurations of graphene that can be twisted and stacked to elicit robust superconductivity at low temperatures. The study establishes these configurations as the first known “family” of multilayer magic-angle superconductors.
