## Description

- description: Sb2Te3 is a layered material with the properties of both a topological
    insulator and a phase-change material. In this study, to investigate the relationship
    between the spin current-to-charge current conversion efficiency of Sb2Te3 and
    its phase, we fabricated Sb2Te3/CoFeB bilayers with varying Sb2Te3 thicknesses.
    The electromotive force induced at both ends of the bilayer was measured as a
    result of the scattering of the spin current injected into Sb2Te3 by spin pumping
    due to ferromagnetic resonance, the so-called inverse spin Hall effect (ISHE).
    Two different Sb2Te3 phases—crystalline and amorphous—were prepared, and the phase
    dependence of the ISHE was investigated. The ISHE of the crystalline Sb2Te3 film
    exhibited a strong dependence on thickness, whereas the amorphous phase showed
    only a minor variation with thickness. These findings contribute to the development
    of novel devices that exploit both the charge and spin degrees of freedom in topological
    insulator-based spintronic applications.
