Cascade sets the stage for superconductivity in magic-angle twisted bilayer graphene

The researchers used scanning tunneling microscopy to observe what happens when they add additional electrons to magic-angle twisted bilayer graphene. They observed a cascade of transitions in the electronic properties, patterns that could help unlock how superconductivity emerge in these materials.
