Recently, shift current, which is one of the nonlinear spontaneous photovolatic effect originated from the broken spatial reversal symmetry, is attracted for physics and solar-cell device applications. In this research, we fabricated MoS₂/CrPS₄ artificial hetero-structure device. CrPS₄ is well known as an air-stable and anti-ferromagnetic layered material, so we can hope a hetero-interface in which both time and spatial inversion symmetries are broken. We will discuss about nonlinear photovoltaic effect in magnetic system, which is originated from the broken symmetry of band strucure in momentum space.
