A similar idea underpins topological insulators, but the transformation in this case doesn’t involve a material’s spatial properties. Instead, it concerns the wavefunctions of the electrons flowing in the material. These contain what is in effect a knot, making it impossible to smoothly convert a topological insulator into a normal insulator. Whereas electrons usually have a mass, in the case of topological insulators the conducting electrons on the surface have no mass and are automatically "spin polarized," leading to the unique half-integer quantum Hall effect observed and also making the material promising for various potential applications. 2020-08-10 2012-05-14 2020-09-23 Topological Insulator Cell for Memory and Magnetic Sensor Applications Takashi Fujita 1, Mansoor Bin Abdul Jalil;2, and Seng Ghee Tan 3 1Computational Nanoelectronics and Nano-device Laboratory, Electrical and Computer Engineering Department, National University of Singapore, 4 Engineering Drive 3, Singapore 117576 The three-dimensional topological insulator is a quantum state of matter characterized by an insulating bulk state and gapless Dirac cone surface states.

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.
