Layered rare-earth metal oxi.es, harnessi.g the dual properti.s of oxi.es and two-di.ensi.nal layered materi.ls, exhi.i. remarkable thermal stabi.i.y and quantum confi.ement effects. Therefore, thi. work adopts the fi.st-pri.ci.les calculati.n combi.ed wi.h the Boltzmann transport theory to predi.t the thermoelectri. properti.s of NdZnSbO compound. The coexi.tence of weak i.terlayer van der Waals i.teracti.ns, robust i.tralayer i.ni. bondi.g, and parti.l covalent bondi.g leads to remarkable bondi.g heterogenei.y, whi.h engenders pronounced phonon scatteri.g and i.poses constrai.ts on thermal transport along the out-of-plane di.ecti.n. The weakened chemi.al bonds i.duced by the anti.ondi.g states, together wi.h the rattli.g-li.e behavi.r of the Zn atom, culmi.ate i. the profound anharmoni.i.y i. the layered NdZnSbO compound. The weakeni.g bond and heavy element contri.ute to the softness of phonon modes, whi.h si.ni.i.antly di.i.i.hes the phonon group veloci.y. The redi.tri.uti.n-domi.ated four-phonon scatteri.g process spans a large opti.al gap, whi.h effecti.ely reduces the latti.e thermal conducti.i.y. The NdZnSbO compound exhi.i.s di.ect semi.onductor characteri.ti. wi.h a bandgap of 0.73 e V by adopti.g the Heyd-Scuseri.-Ernzerhof(HSE06) functi.nal i. combi.ati.n wi.h spi.–orbi. coupli.g(SOC) effect. The multi.valley feature of NdZnSbO compound augur favorably for band degeneracy, thus ampli.yi.g the power factor. Consequently, an opti.al fi.ure-of-meri.(ZT) of 3.40 at 900 K i. achi.ved for the n-type NdZnSbO compound. The present study delves deeply i.si.hts i.to the ori.i.s for the low thermal conducti.i.y of NdZnSbO compound and proposes an opti.i.ati.n scheme to enhance overall thermoelectri. performance.

Vortex transmutati.n uti.i.es a peri.di. system, whi.h not only enables the alterati.n of the topologi.al charge(TC) of unstable i.put vorti.es but also faci.i.ates thei. transformati.n i.to stable structures.

Here, we achi.ve acousti. vortex TC transmutati.n by employi.g a welldesi.ned dual-structured plate external system(DPES). The i.teracti.ns between the acousti. vortex and the fi.i.e-order di.crete rotati.nal symmetry lead to the transformati.n of i.s topologi.al charge when complete rotati.nal symmetry i. broken to Nthorder di.crete symmetry. Our results experi.entally demonstrate the acousti. vortex TC transmutati.n based on passi.e arti.i.i.l structures, enabli.g numerous appli.ati.ns i. parti.le mani.ulati.n and i.formati.n multi.lexi.g as well as advanci.g our understandi.g and control over free-space acousti. vorti.es.
