Electric field tunable unconventional superconductivity in alternating twist magic-angle trilayer graphene

Zeyu Hao, A. M. Zimmerman, Patrick Ledwith +6

We construct a van der Waals heterostructure consisting of three graphene layers stacked with alternating twisting angles $\pm \theta$. At the average twist angle $\theta \sim 1.56^{\circ }$, a…
