We have fabricated p -type La0.7 Sr0.3 Mn O3 thin film/ n -type ZnO nanowires (nanosheets) heterostructures. A lower-temperature growth with Zn source and a higher-temperature growth with ZnO/graphite source led to the formations of nanowires and nanosheets, respectively. While the nanosheets showed an epitaxial relationship with the manganite film, the high processing temperature resulted in interfacial diffusion and reaction, which were reflected in the x-ray diffraction, magnetic, and electrical transport measurements. The manganite thin film/ZnO nanowires (nanosheets) p-n junctions exhibited good rectification behaviors. Such heterostructures are promising to find potential applications in electronic and spintronic devices.
