采用漂移扩散模型对La_（0.7）Sr_（0.3）MnO_3/Si异质结的输运性质进行了理论研究。一个简单的情况下的半导体带和电场的异质结的界面区域与各种偏置电压。自洽计算结果与实验数据吻合较好，表明所提出的能带图可以有效地解释La_（0.7）Sr_（0.3）MnO_3/Si异质结的输运性质，而不考虑锰氧化物界面结构的复杂性以及电荷、自旋、晶格和轨道之间的多重耦合.
The transport property of the La0.7Sr03MnO3/Si 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 La0.7Sr0.3MnO3 and Si regardless of the complexity of the interface structures and multi-couplings among charge, spin, lattice and orbital of manganites.
