Spin-dependent Seebeck effect in zigzag-edge antimonene nanoribbons

Abstract

In spin caloritronics, the spin-dependent Seebeck effect provides a method for significantly reducing Joule heating and achieving ultra-high integration density. Here, we investigate the electronic transport and spin thermoelectric properties of zigzag-edge antimonene nanoribbons (ZANRs) with different widths using first-principles calculations. The results show that the ZANRs exhibit an excellent spin-dependent Seebeck effect. By modulating the ribbon width, thermal spin devices could generate large spin-dependent currents with small charge currents, making them ideal for spintronic applications with low power consumption and high efficiency. Interestingly, the spin current of ZANRs goes up oscillatingly as the ribbon width decreases, which is beneficial for device miniaturization. Our findings may offer insights into the development of spin caloritronic devices.
