Abstract
This paper reports the nonreciprocal transport in a noncentrosymmetric 2D superconductor, gated MoS2, under out-of-plane magnetic field. The magnitude of the nonreciprocal signal, arising from the vortex rectification by the asymmetric pinning potentials in the trigonal lattice, substantially depends on whether the vortex motion is quantum or classical.
