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...
