Ultraviolet and visible range plasmonics in the topological insulator Bi1.5Sb0.5Te1.8Se1.2.
The development of metamaterials, data processing circuits and sensors for the visible and ultraviolet parts of the spectrum is hampered by the lack of low-loss media supporting plasmonic excitations. This has driven the intense search for plasmonic materials beyond noble metals. Here we show that the semiconductor Bi1.5Sb0.5Te1.8Se1.2, also known as a topological insulator, is also a good plas...
متن کاملSpin-charge separation of plasmonic excitations in thin topological insulators
We discuss plasmonic excitations in a thin slab of topological insulators. In the limit of no hybridization of the surface states and same electronic density of the two layers, the electrostatic coupling between the top and bottom layers leads to optical and acoustic plasmons which are purely charge and spin collective oscillations. We then argue that a recent experiment on the plasmonic excita...
متن کاملSuperconducting ‘‘metals’’ and ‘‘insulators’’
We propose a characterization of zero-temperature phases in disordered superconductors on the basis of the nature of quasiparticle transport. In three-dimensional systems, there are two distinct phases in close analogy to the distinction between normal metals and insulators: the superconducting ‘‘metal’’ with delocalized quasiparticle excitations and the superconducting ‘‘insulator’’ with local...
متن کاملTopological Insulators and Superconductors
We study theoretical properties of robust low energy electronic excitations associated with topological insulators and superconductors. The bulk materials are described by non-interacting single particle band Hamiltonians with a finite excitation gap. Their topological phases are classifed according to symmetries and dimensions, characterized by discrete bulk invariants, and correspond to topol...
متن کاملCrystal growth and anomalous transport properties of CuxBi2Se3
Topological insulators (TIs) have received considerable attention due to their potential to offer new platforms for the realization of novel states of quantum maters. TIs are characterized by their fully insulating gap in the bulk but necessarily gapless edge or surface states protected by time-reversal symmetry. Recently, the three-dimensional (3D) TIs were theoretically predicted and discover...
