The Fermi surface geometrical origin of axis-dependent conduction polarity in layered materials
Electronic materials generally exhibit a single isotropic majority carrier type, electrons or holes. Some superlattice 1 , 2 and hexagonal 3 – 5 materials exhibit opposite conduction polarities along in-plane and cross-plane directions due to multiple electron and hole bands.

, a layered metal, has such a Fermi surface. It displays in-plane electron and cross-plane hole conduction in thermopower and exactly the opposite polarity in the Hall effect. The small Nernst coefficient and magnetoresistance preclude multi-band transport. We label this direction-dependent carrier polarity in single-band systems ‘goniopolarity’. We expect to find goniopolarity and the Fermi surface geometry that produces it in many metals and semiconductors whose electronic structure is at the boundary between two and three dimensions. Goniopolarity may enable future explorations of complex transport phenomena that lead to unprecedented device concepts.
A single-band metal whose carriers behave as electrons or holes depending on the direction of travel is observed. The effect arises from a particular type of Fermi surface geometry. |
