From nanorods to nanowires: A controllable synthesis of one-dimensional superconducting cuprates

One-dimensional nanostructured superconducting La 1.85Sr 0.15CuO 4 was synthesized by a sol–gel template method. It was found that there is a morphology crossover from nanorods to nanowires as the heating rate increases during the fabrication process. A plausible growth mechanism was developed to ex...

Zusammenfassung:	One-dimensional nanostructured superconducting La 1.85Sr 0.15CuO 4 was synthesized by a sol–gel template method. It was found that there is a morphology crossover from nanorods to nanowires as the heating rate increases during the fabrication process. A plausible growth mechanism was developed to explain this morphology controllable synthesis which can be extended to grow other similar one-dimensional nanostructures.
