# Stability of topological properties of bismuth (1 1 1) bilayer

@article{Bieniek2016StabilityOT, title={Stability of topological properties of bismuth (1 1 1) bilayer}, author={Maciej Bieniek and Tomasz Woźniak and Paweł Potasz}, journal={Journal of Physics: Condensed Matter}, year={2016}, volume={29} }

We investigate the electronic and transport properties of the bismuth (1 1 1) bilayer in the context of the stability of its topological properties against different perturbations. The effects of spin–orbit coupling variations, geometry relaxation and interaction with a substrate are considered. The transport properties are studied in the presence of Anderson disorder. Band structure calculations are performed within the multi-orbital tight-binding model and density functional theory methods. A…
