| titleOfInvention | A passive and low-power microwave detection method and device and preparation method thereof |
| abstract | The invention discloses a passive and low-power microwave detection method, a device and a preparation method thereof. An antiferromagnetic topological insulator layer is prepared. Under microwave energy, spins in the antiferromagnetic topological insulator layer precess to generate spins. Due to the spin-momentum locking feature of topological surface states, spin currents spontaneously generate directional charge flow on the surface. The electric charge flow is detected by the electrodes, and the passive low-power consumption detection of microwaves is realized. Since the multilayer antiferromagnetic topological insulator layer can be viewed as a periodic stacking of the bilayer structure of the antiferromagnetic layer and the topological insulator layer, the microwave detection sensitivity is multiplied. The topological surface states exhibit strong robustness and low-dissipative current transport properties, reducing the power consumption for microwave detection. The invention not only fully utilizes the strong robustness and unique electrical transmission characteristics of the topological surface state, but also utilizes the microwave resonance of the antiferromagnetic layer, so that the structure can realize passive microwave detection with lower power consumption. |
