Revealing quantum geometry effects in magic angle twisted bilayer graphene using the circular photogalvanic effect
Eylon Persky, Leonie Parisot, Minhao He +7
We report a photocurrent studies of a magic angle twisted bilayer graphene device using near infrared light. Through photocurrent imaging and polarization dependence, we separate t…

Moiré-driven equilibrium of perturbations in moiré systems
Federico Escudero, Zhen Zhan, Pierre A. Pantaleón +1
Perturbations in moiré materials, such as due to substrates or strain, are common in many experiments and can significantly modify the electronic properties of the system. Here, w…

Straintronics and twistronics in bilayer graphene
Federico Escudero, Dong Wang, Pierre A. Pantaleón +3
The interplay of twist and strain in bilayer graphene enables the formation of moiré patterns and narrow bands that host correlated and topological phases. While magic-angle twist…
