AbstractHeterostructures composed of Nd0.7Sr0.3MnO 3 and Nb-SrTiO3 were fabricated by laser ablation and characterized under different fields (optic, electric, and magnetic). The asymmetric ratios [β=I(1V)/I(-1V) in I-V curves were over 107, demonstrating highly rectifying properties in a wide temperature range. Under magnetic fields, remarkable modulations of I-V curves were achieved. Significant open circuit voltages were observed when illuminated by visible lights with wavelengths of 532 nm and 650 nm. A planar back-to-back diode (Nd 0.7Sr0.3MnO3/Nb-SrTiO3/Nd 0.7Sr0.3MnO3) with a good on/off ratio to visible lights was also fabricated. These results were discussed in analogy with conventional semiconductor junctions. © 2011 American Institute of Physics.
