Abstract

The formation of superconducting YBa₂Cu₃O_7-x (Y123) by in situ pulsed laser deposition from a stoichiometric Y123 target typically requires an oxygen-ambient environment (P ∼ 100-300-mtorr O₂) and appropriate substrate temperature during deposition. We have found that pulsed laser deposition from a Y123 target in vacuo onto a (001) LaAlO₃ substrate favors the formation of Y₂O₃. We observed that the Y₂O₃(001) films yield three-dimensional nanoscale morphologies that are markedly different from the planar growth surface of conventional superconducting c-axis Y123 films and Y₂O₃ films formed from the pulsed laser ablation of a Y₂O₃ target.
