Effects of vicinal growth in ErBa2Cu30 7-δ (ErBCO) with one-dimensional nanorods are discussed from their microstructures. BaNb2O6 doped ErBCO films were grown on vicinal substrates with tilted angles of 0°, 4° and 8° by a pulsed laser technique. Surface step structure appeared distinctly with increasing vicinal angles to 8° in images of scanning electron microscopy and atomic force microscopy. Then, Ba(Er0.5Nb0.5)O 3 nanorods continuously grew from the step on vicinal substrate to film surface steps in transmission electron microscopy images of the film. The alignment of one-dimensional nanorods relate closely to film growth morphology.
