Novel hetero p-n junctions of p-La(Ba)Mn03/n-Zn0 were fabricated. They have step-terrace morphology and excellent crystallinity. Their orientations can be interpreted by calculations of lattice matching and site Coulomb energy. The junction shows I-V rectification and unique temperature dependence, and 200000 rectification factor after running-current. It also shows switching and hysteresis I-V behaviors. These are interpreted by percolation model due to ferromagnetic grains in LBMO. It shows large photo-induced current amplification, interpreted by phase change.
