a Two-probe device structure for calculating the photocurrent of the nitrogen-doped MoS₂. b The side view of the relaxed configuration of a. The S, Mo, and N atoms are respectively depicted by yellow, light blue, and dark blue. Without bias voltages, the scattering region is irradiated by the polarized light perpendicularly. For the linearly polarized light, the polarization angle θ is measured with respect to the transport direction
