Embodiment

[0024] The artificial intelligence-based spintronic sound recognition device of the present invention, such as Figure 1-2 As shown, it consists of a substrate, a two-dimensional Weyl semimetal layer, a ferromagnetic material layer, a potential barrier layer, and a ferromagnetic material layer from bottom to top.

[0025] In the process of use, the collected sound is first passed through processing, and each point of the audio waveform is converted into a fast-paced binary sequence, which is designed to generate a chain reaction of amplitude changes, such as image 3 shown. In this nano-oscillator based on spin-orbit torque, the digital waveform is obtained, and then the voltage corresponding to the waveform generated by the oscillator is input to the spintronic sound recognition device.

[0026] Such as Figure 4-5 , by inputting an I slightly below the threshold to the lower two-dimensional Weyl semimetal layer in , and then the processed signal is excited and input to th...

Abstract

The invention discloses a spin electron sound recognition device based on artificial intelligence and a preparation method and application thereof. The spin electronic device is used for simulating an artificial neural network device, and compared with an artificial neural network device based on a CMOS, the spin electronic device has the advantages of being non-volatile, low in power consumption, high in speed and high in integration level. Meanwhile, compared with a spin device made of a magnetic tunnel junction, the device mainly utilizes the spin orbit torque principle, and a magnetic field does not need to be additionally arranged on the outer side of the device for driving. In addition, the device can show four different resistance states, and an intermediate state does not need to be set. Through modulation of the converted excitation microwave voltage, conversion among four resistors can be realized, and a two-bit storage function can be realized in a single device.
