An odd nonlinear conductivity in chiral tellurium
Electrical transport in non-centrosymmetric materials departs from the well-established phenomenological Ohm’s law. Instead of a linear relation between current and electric field, a non-linear conductivity emerges along specific crystallographic directions. This non-linear transport is fundamentally related to the lack of spatial inversion symmetry. Ohm’s law is one of the most established relations in Physics and […]
