Topological insulator applications

The bulk of such materials is insulating but the surface can conduct electric current with well-defined spin texture. 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. Device applications of topological insulators require a highly insulating bulk and tunable Dirac carriers, which has so far been difficult to achieve.

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. Secondly, the preparation and doping of TI are assessed. Some results are listed.

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.

2. Plasmons on the surfaces of bulk topological insulators The most promising applications of topological insulators are spintronic devices and dissipationless transistors for quantum computers based on the quantum Hall effect [13] and quantum anomalous Hall effect. [51] In addition, topological insulator materials have also found practical applications in advanced magnetoelectronic and optoelectronic “This is a really exciting development for the field because it is the first promising indication that we actually may be able to build a practical technology with these topological insulator materials, which many condensed-matter physicists have been studying with spintronics applications as the motivation,” said co-principal-investigator Nitin Samarth, a professor of physics and the With technological applications in mind, for example in information technologies, one of the challenges during these years of intense research has been the creation of a magnetic topological insulator. So far, magnetic topological insulators had only been created by the so-called extrinsic route, which consists of doping nonmagnetic topological the ordinary insulator from “weak” and “strong” topological insulators.

Thus, exploring the visible-range plasmonic response of topological insulators is significant to reveal their optical characteristics and broaden their applications at high frequencies. Herein, we report the experimental demonstration of a visible-range surface plasmon resonance (SPR) effect on an antimony telluride (Sb 2 Te 3 ) topological insulator film. These states have spin-momentum locked dispersion caused by time-reversal symmetry or mirror symmetry for topological insulators and topological crystalline insulators, respectively. The time-reversal symmetry can be broken by the magnetic field; thus, ferromagnetically doped topological insulators are of great scientific interest for the possible electronic and spintronic application.
