Application of hybridization perovskite nanometer material in preparing all-optical spinning electron device

Abstract

The invention discloses an application of hybridization perovskite nanometer materials in preparing an all-optical spinning electron device, solves the problem that in the prior art the magneto optic isolation devices are big in magnet volume which leads to big total device volume, high device preparation cost, slower switch speed of the full light switch, and difficult to reach picosecond volume level, the prepared magneto optic isolation device using hybridization perovskite nanometer material does not require extra magnetic field, the magnetic field is produced by the optical orientation method, the device is small in volume, and is suitable for the integration of photoelectric devices. The response speed of the prepared all-optical switch is at a picosecond scale, with a high laser damage threshold value, and the all-optical switch can be applied in the ultra-strong femtosecond laser. Most importantly, the prepared all-optical spintronics device uses the quantum property of electrons, and is not bounded by the shortcomings of the traditional electronic devices. The hybridization perovskite nanometer materials are low in cost, so that production costs are significantly reduced.

Background technique [0002] With the development of science and technology, the degree of circuit integration continues to increase, and the speed of operation continues to accelerate. The defects of silicon-based traditional electronic devices based on atomic charge are becoming more and more obvious, which has seriously hindered the development of electronic devices. The purpose of semiconductor spintronics is to use the spin characteristics of particles (electrons, holes, excitons, etc.) to replace or combine chargeability to prepare spintronic devices.

Problems solved by technology

In order to achieve the rotation angle required to block the optical path, the magnetic field strength is required to be high, and the corresponding magnet volume is large, so the total volume of the device is large, which is not conducive to the development of integrated circuits.

Moreover, the current optical isolator mainly uses materials doped with rare earth elements, and the preparation cost is relatively high.

Now the information exchange speed on the nodes of the Internet reaches the order of terabits per second (TB / s), and the corresponding switching speed must reach the order of picoseconds, and the switching speed of traditional optical switches is difficult to meet this requirement

[0004] In summary, the magneto-optical isolator magnets in the prior art are large in size, resulting in a large total device volume, high device manufacturing costs, and the slow switching speed of the all-optical switch, which is difficult to reach the level of picoseconds, and there is still a lack of effective solution
