Bi-ene/X Interfaces and their effects
This subproject will focus on the atomic structure of the interface of bismuthene with a substrate and/or proximity material layers, and how strain and other proximity effects affect the topological band structure. DFT calculations will be combined with other theoretical methods (e.g. semi-empirical tight binding) to obtain realistic band structures. We will seek for tendencies to optimize the topological gap, but also take care of chemical stability.
