In addition, topological insulator materials have also found practical applications in advanced magnetoelectronic and optoelectronic devices. Due to the nature of graphene-like surface state, topological insulators (TIs) was used for pulsing the laser since 2012. To date, TIs have been realized to be a promising modulator not only for fiber lasers but also for solid state lasers. In this chapter the electronic and optical properties of TIs have been reviewed. One such advancement is the topological insulator, a new phase of matter that stands on the boundary between insulation and conductance. This technology would allow for the eventual construction of the quantum computer, a revolutionary device that would use the dynamics of atomic-scale objects to store and manipulate information. Topological insulator (TI), a promising quantum and semiconductor material, has gapless surface state and narrow bulk band gap.

In this chapter the electronic and optical properties of TIs have been reviewed. One such advancement is the topological insulator, a new phase of matter that stands on the boundary between insulation and conductance. This technology would allow for the eventual construction of the quantum computer, a revolutionary device that would use the dynamics of atomic-scale objects to store and manipulate information. Topological insulator (TI), a promising quantum and semiconductor material, has gapless surface state and narrow bulk band gap. Firstly, the properties, classifications and compounds of TI are introduced.

The unique applicability of topological insulators to spintronic devices comes from the fact that the conducting electrons on the surface have no mass and are automatically “spin polarized,” leading to the unique half-integer quantum Hall effect that was observed in this research. Topological Insulators: Electronic structure, material systems and its applications Parijat Sengupta Network for Computational Nanotechnology First Published: 08 January 2021 Topological insulators are materials that are electrically insulating in the bulk but can conduct electricity due to topologically protected electronic edge or surface states. This Perspective examines the emerging applications of photonic topological insulators (PTIs) in the microwave domain. The introduction of topological protection of light has revolutionized the traditional perspective of wave propagation through the demonstration of 2020-07-20 · Recently, higher-order topological insulators have been proposed as a way of realizing topological states with dimensions two or more lower than that of the bulk due to the quantization of bulk 2021-04-12 · Topological insulators have notable manifestations of electronic properties. The helicity-dependent photocurrents in such devices are underpinned by spin momentum-locking of surface Dirac The main part of the book discusses realistic models for both time-reversal-preserving and -violating topological insulators, as well as their characteristic responses to external perturbations.
