Three-Dimensional Topological Insulators
Topological insulators in three dimensions are nonmagnetic insulators that possess metallic surface states (SSs) as a consequence of the nontrivial topology of electronic wavefunctions in the bulk of the material. They are the first known examples of topological order in bulk solids. We review the basic phenomena and experimental history, starting with the observation of topological insulator b...
متن کاملSurface states and topological invariants in three-dimensional topological insulators: Application to Bi1−xSbx
We study the electronic surface states of the semiconducting alloy bismuth antimony Bi1−xSbx . Using a phenomenological tight-binding model, we show that the Fermi surface for the 111 surface states encloses an odd number of time-reversal-invariant momenta TRIM in the surface Brillouin zone. This confirms that the alloy is a strong topological insulator in the 1;111 Z2 topological class. We go ...
متن کاملTwo-dimensional electronic transport on the surface of three-dimensional topological insulators
We present a theoretical approach to describe the two-dimensional (2D) transport properties of the surfaces of three-dimensional topological insulators (3DTIs) including disorder and phonon scattering effects. The method that we present is able to take into account the effects of the strong disorder-induced carrier density inhomogeneities that characterize the ground state of the surfaces of 3D...
متن کاملInteracting Surface States of Three-Dimensional Topological Insulators.
We numerically investigate the surface states of a strong topological insulator in the presence of strong electron-electron interactions. We choose a spherical topological insulator geometry to make the surface amenable to a finite size analysis. The single-particle problem maps to that of Landau orbitals on the sphere with a magnetic monopole at the center that has unit strength and opposite s...
متن کاملEnhanced electron dephasing in three-dimensional topological insulators
Study of the dephasing in electronic systems is not only important for probing the nature of their ground states, but also crucial to harnessing the quantum coherence for information processing. In contrast to well-studied conventional metals and semiconductors, it remains unclear which mechanism is mainly responsible for electron dephasing in three-dimensional topological insulators (TIs). Her...
