Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

Realization of Quantum Spin Hall Insulator Superlattice with Emergent Multigap‐Like Helical Edge States

ABSTRACT The functional quantum spin Hall insulators (QSHI), protected by time‐reversal symmetry against single‐particle backscattering, hold great promise for dissipationless quantum electronics. Realization of QSHI with gapped helical edge states, which would enable determinist...
