The supermoiré lattice, built by stacking two moiré patterns, provides a platform for creating flat mini-bands and studying electron correlations. An ultimate challenge in assembling graphene lattice is the deterministic control of its rotational alignment, which made highly aleatory due to random nature edge chirality crystal symmetry. Employing so-called "golden rule three", here we present an experimental strategy overcome this realize controlled alignment double-aligned hBN/graphene/hBN...
Abstract The hybrid interface between 2D materials and complex oxides offers a rich platform to explore fascinating physical phenomena like helical edge states, broken-symmetry phases, giant magnetoresistance. While current research primarily focuses on the influence of layered materials, reverse—how affect oxides—remains largely unexplored. Here, we examined impact graphene layers formation oxygen vacancies in SrTiO 3 (STO) during high-temperature annealing. Our findings, supported by Raman...
