Abstract In this project we will investigate the behavior of electronic states at the interface of two topological insulators(TI). Topological insulators are characterized by the existence of metallic states, localized at its interface, which are topologically protected. Such states posses nontrivial transport properties being robust against perturbations that preserve time reversal symmetry. Several groups are dedicated to the investigation of topological insulators, nevertheless little have been done to understand how these metallic states interact at the interface of two different TI's. For a 3D material, its interface is a surface, several questions must be addressed: how the properties of the states depends on the thickness of the film?, is there any spin texture?, is there any changes depending on how they interact? These are important questions that are still opened and have not been well explored from the theoretical an experimental point of view. It is of major importance to comprehend such questions in order to find new materials for spintronics and other applications. (AU) | |
