The transport property of the 
heterostructure was investigated theoretically by applying the drift-diffusion model to the present system. A simple scenario of the semiconductor band and electric field at the interface region of the heterostructure with various bias voltages are presented. The good agreement between the self-consistent calculated results and the experimental data indicates that the proposed band picture is valid for the interpretation of the transport property of the p-n heterojunctions made of 
and Si regardless of the complexity of the interface structures and multi-couplings among charge, spin, lattice and orbital of manganites.
