Atomically Thin Quantum Spin Hall Insulators

Atomically thin topological materials are attracting growing attention for their potential to radically transform classical and quantum electronic device concepts. Among them is the spin Hall (QSH) insulator—a 2D state of matter that arises from interplay band inversion strong spin–orbit coupling, with large tunable bulk bandgaps up 800 meV gapless, 1D edge states. Reviewing recent advances in science engineering alongside theoretical description, QSH library surveyed focus on prospects QSH-based applications. In particular, predictions nontrivial superconducting pairing toward Majorana-based computing discussed, which next frontier research.
