Characterization of topological band structures away from the Fermi level by the anomalous Nernst effect
Characterization of topological band structures away from the Fermi level by the anomalous Nernst effect
Resolving the structure of energy bands in transport experiments is a major challenge in condensed matter physics and material science. Sometimes, however, traditional electrical conductance or resistance measurements only provide very small signals, and thus limit the ability to obtain direct band-structure information. In this case, it has been proven …
