Abstract

We have studied the electron channeling patterns (ECPs) of both pure a-axis and pure c-axis epitaxial YBa2Cu3O7−δ thin films on various substrates. ECPs from three representative a-axis films [on PrBa2Cu3O7−δ buffered LaAlO3 (001), MgO (001), and SrLaAlO4 (001)] and three c-axis films [on LaAlO3 (001), NdGaO3 (001), and SrTiO3 (001)] are presented. The differences between both sets of ECPs are discussed and recorded as references for future identifications.
