It is found that the interfaces grown on SrTiO₃ substrates without terraces exhibit the two dimensional electron gas. Moreover, the conductive interfaces show a resistance upturn at low temperatures which is strongly diminished by light irradiation. These interfaces favor the persistent photoconductivity, and the enormous value of relative change in resistance, about 60 185.8%, is also obtained at 20 K. The experimental results provide fundamental insights into controlling the defects at conductive interfaces of oxides and paving a way for complex-oxides based optoelectronic devices.en1361-648X202124Conductive interfaceLaFeO /SrTiO heterointerfaces 3 3Persistent photoconductivityPulsed laser depositionChemistryEngineering and Applied OperationsJournal Article10.1088/1361-648X/abea40Journal Article
