| 英文摘要 | Bilayer phosphorene attracted considerable interest, giving a potential application in nanoelectronics owing to its natural bandgap and high carrier mobility. however, very little is known regarding the possible usefulness in spintronics as a quantum spin hall (qsh) state of material characterized by a bulk energy gap and gapless spin-filtered edge states. here, we report a strain-induced topological phase transition from normal to qsh state in bilayer phosphorene, accompanied by band-inversion that changes. 2 number from 0 to 1, which is highly dependent on interlayer stacking. when the bottom layer is shifted by 1/2 unit-cell along zigzag/armchair direction with respect to the top layer, the maximum topological bandgap 92.5 mev is sufficiently large to realize qsh effect even at room-temperature. an optical measurement of qsh effect is therefore suggested in view of the wide optical absorption spectrum extending to far infra-red, making bilayer phosphorene a promising candidate for opto-spintronic devices. |
