Nonreciprocal electrical transport in van der Waals crystals
ORAL
Abstract
Nonreciprocal electrical transport, which is the second order nonlinear electrical transport in noncentrosymmetric crystals, represents the rectification effect originating from lattice symmetry breaking. Recently, nonreciprocal electrical transport has been observed in a variety of van der Waals materials without special inversion symmetry[1-3], including electric-field-induced superconductors. In this presentation, we review the nonreciprocal electrical transport in van der Waals crystals. Characteristic behavior and microscopic mechanism of nonreciprocal electrical transport will be also discussed.
