AbstractStructural properties of YBa2Cu3O7-/PrBa2Cu3O7- heterointerfaces have been investigated by aberration-corrected electron microscopy. Experimental evidence shows that c-axis-oriented YBa2Cu3O7-/PrBa2Cu3O7- heterostructures with atomically sharp interface epitaxially grow on SrTiO3(001) substrates. In terms of the contrast analysis, no apparent interdiffusion between YBa2Cu3O7- and PrBa2Cu3O7- occurs at the interface. In addition, stand-off misfit dislocations and planar faults appear within PrBa2Cu3O7- layer near the interface. Both misfit dislocations and interfacial dislocations resulting from the termination of planar faults contribute to misfit relaxation at the YBa2Cu3O7-/PrBa2Cu3O7- interface. The defect configuration of planar faults and stand-off misfit dislocations is explored. Copyright (c) 2013 John Wiley & Sons, Ltd.
