Goniopolar kagome materials boost transverse thermoelectricity

Thermoelectricity enables interconversion between heat and charge currents, but existing material platforms rely on constrained longitudinal geometries, complex fabrication or an external magnetic field to achieve high performance. Now, goniopolar kagome materials enable strong transversal thermoelectricity without an applied magnetic field, owing to flat electronic bands or van Hove singularities.
