Topological properties of Xene tuned by perpendicular electric field and exchange field in the presence of Rashba spin–orbit coupling

X Zhao, Z Wang, J Chen, B Wang - Journal of Physics …, 2022 - iopscience.iop.org
Abstract Xene (X= Si, Ge, Sn) is a typical and promising two-dimensional topological
insulator with many novel topological properties. Here, we investigate the topological …

Phase diagrams and topological mixed edge states in silicene with intrinsic and extrinsic Rashba effects

XL Lü, YC Zhang, PH Fu, JF Liu - Physical Review Research, 2024 - APS
We investigate the topological phases and corresponding edge states in silicene with fixed
intrinsic and extrinsic Rashba spin-orbit couplings. The results show that silicene can exhibit …

Transport signatures of higher-order topology in bismuth nanostructures

A Bernard - 2022 - theses.hal.science
Topological Insulators (TI) are characterized by topologically-protected conducting states on
their boundaries even though their bulk is insulating. The topological character provides a …
