"create both positive and negative polarities generating electricity from heat using Co3Sn2S2 having topological magnet properties... swapping out some elements in magnetic compound... cobalt-tin-sulfur-based ferromagnet because its topological electronic state is suited to control polarity of anomalous Nernst effect... substitution of nickel and indium led to reversal in sign of thermoelectric voltage through modulation of topological electronic state... cheap base elements for fabrication of thermopile devices"
