Twist and strain identification in moiré heterostructures
Zhen Zhan, Federico Escudero, Dong Wang +4
The geometrical and electronic properties of moiré materials are highly sensitive to the twist and strain in the samples due to the moiré magnifying effect. Accurate identification…
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…
Structural and electronic signatures of strain-tunable marginally twisted bilayer graphene
Pei Ouyang, Jiawei Yu, Qian Li +11
Marginally twisted bilayer graphene having small twist angles is predicted to exhibit unique structural and electronic properties, though experimental characterization remains limi…
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 twiste…
Review of the tight-binding method applicable to the properties of moiré superlattices
Xueheng Kuang, Federico Escudero, Pierre A. Pantaleón +2
Moiré superlattices have emerged as a versatile platform for exploring a wide range of ex- otic quantum phenomena. Unlike angstrom-scale materials, the moiré length-scale system co…
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…
