                      7−x /YBa 2 Cu 3 O 7−x trilayers grown on (100) LaAlO 3
                      substrates with improved interfacesmoothness. The trilayers
                      are synthesized by ozone-assisted molecular-beam epitaxy.
                      The thickness of the PrBa 2 Cu 3 O 7−x layer is held
                      con-stant at 8 nm, and the thickness of the YBa 2 Cu 3 O
                      7−x layers is varied from 24 nm to 100 nm. X-ray
                      diffraction measurements show all trilayersto have $>97\%$
                      a-axis content. The rms roughness of the thinnest trilayer
                      is <0.7 nm, and this roughness increases with the thickness
                      of theYBa 2 Cu 3 O 7−x layers. The thickness of the YBa 2
                      Cu 3 O 7−x layers also affects the transport properties:
                      while all samples exhibit an onset of thesuperconducting
                      transition at and above 85 K, the thinner samples show wider
                      transition widths, ΔT c . High-resolution scanning
                      transmissionelectron microscopy reveals coherent and
                      chemically sharp interfaces and that growth begins with a
                      cubic (Y,Ba)CuO 3−x perovskite phase thattransforms into
                      a-axis oriented YBa 2 Cu 3 O 7−x as the substrate
