Design of anomalous Nernst thermoelectric generators for giant power output.

ABSTRACT: Topological magnets have shown great potential for transverse thermoelectric (TE) conversion with structural advantages, utilizing the anomalous Nernst effect. To facilitate such applications, the development of exceptional topological magnet-based Nernst devices is a crucial step that requires both high-performance topological magnets and the design of low-resistance interfaces in the devices. Here, we report that the anomalous Nernst effect in topological magnets can be ubiquitously enhanced by synergistically tuning the entropy-density-weighted Berry curvature and the Fermi surface, as evidenced by a giant anomalous Nernst power factor of 47.8 μW m^-1 K^-2 at room temperature in electron-doped Co₂MnGa. In addition, we achieved an ultralow interfacial resis
