Twistraintronics in Square Moire Superlattices of Stacked Graphene Layers
Roberto Carrasco, Federico Escudero, Zhen Zhan +6
We report the first observation of controlled, strain-induced square moire patterns in stacked graphene. By selectively displacing native wrinkles, we drive a reversible transition…
Geometrical properties of strained and twisted moiré heterostructures
Federico Escudero, Francisco Guinea, Zhen Zhan
The experimental observations of many interaction-driven electronic phases in moiré superlattices have stimulated intense theoretical and experimental efforts to understand and eng…
Milli-Tesla Quantization enabled by Tuneable Coulomb Screening in Large-Angle Twisted Graphene
I. Babich, I. Reznikov, I. Begichev +15
The electronic quality of graphene has improved significantly over the past two decades, revealing novel phenomena. However, even state-of-the-art devices exhibit substantial spati…
Topological phase diagram of twisted bilayer graphene as a function of the twist angle
Leonardo A. Navarro-Labastida, Pierre A. Pantaleon, Francisco Guinea +1
Twisted bilayer graphene (TBG) hosts a rich landscape of electronic phases arising from the interplay between strong electron-electron interactions and nontrivial band topology. Wh…
Interaction-driven charge textures and unconventional superconductivity in strained monolayer graphene
Elias Andrade, Alejandro Jimeno-Pozo, Pierre A. Pantaleon +2
Two-dimensional systems with flat bands support correlated phases such as superconductivity. While twisted moiré systems, like twisted bilayer graphene, have revealed such states,…
