Controlling quantum spin Hall state via strain in various stacking bilayer phosphorene
Tian Zhang, Jia-He Lin, Yan-Mei Yu +2
Quantum spin Hall (QSH) state of matter has a charge excitation bulk bandgap and a pair of gapless spin-filtered edge-states, which can support backscattering-free transport. Bilay…
