The limitations of metals and insulators can be overcome through the use of doped nodal semimetals in a strong magnetic field. The magnetic field ensures that the transverse drift of both electrons and holes contribute additively to the thermopower. Within a sufficiently high magnetic field, a large enhancement of the electronic density of states and a reduction in the Fermi energy occurs. Since the thermoelectrode materials have small band gaps and electron-hole symmetry in their band structure, concentrations of thermally excited electrons and holes both grow - even while their difference remains fixed. These magnetic field effects allow the thermopower to grow without saturation.
