Abstract: It is well known that p-type doped SrTiO3 can successfully be applied in semiconductor diodes in a blue-light region, transparent conductive films and perovskite-oxides hetero-junction optical- electric devices. First-principles plane-wave pseudopotential (PWPP) calculations have been per-formed to investigate the electronic structure and optical properties of In-doped SrTiO3/MgO(001) interface system with the explanations of the related experiment phenomena. It is found that the optical properties of In doped SrTiO3/MgO(001) interface are dependent not only on the concen-tration of In atoms but also on the relative positions of the In atoms to the interface.
