“…A 6°miscut LAO substrate resulted in higher T c and J c of YBCO films than a planar LAO substrate 29 while there was no relation between T c and vicinal angles for YBCO films on 0°, 2°, 4°, and 6°miscut STO 22 or MgO 34 substrates. Lower T c of films on vicinal substrates than on planar substrates was also observed elsewhere.…”

“…27 A schematic diagram of the surface morphology of a vicinal SrTiO 3 (STO) substrate is shown in Fig. 28 Higher superconducting critical temperature and critical current density were frequently observed for YBCO films on vicinal LaAlO 3 (LAO) substrates, 29 where the nucleation and growth of YBCO films was aided by the morphological configuration of the vicinal LAO substrate surface. Vicinal substrates have terrace structures on the surface, providing preferable attachment sites for the incoming adatoms or particles.…”

Growth mechanism of YBa₂Cu₃O_7–δthin films and precipitates on planar and vicinal SrTiO₃substrates

Effects of the vicinal angle, film thickness, and temperature on the growth modes, microstructures, and electrical properties of YBa 2 Cu 3 O 7−␦ on SrTiO 3 were studied. Island growth transition between the initial nucleation and the later coalescence stages was observed with film thickness on a planar SrTiO 3 , while no islands were observed at the later stage due to the step-flow mode. As the growth temperature increased, a-axis precipitates were transformed to c-axis precipitates (islands), while no islands formed on vicinal SrTiO 3 . The supercurrent critical temperature was strongly related to the substrate vicinal angle due to the step-flow mode.

“…As treated in Ref. [24] for the case of a nominal (100)LaΑ1O 3 substrate with miscut δ, unit-cell high parallel ledges of width λ develop with (100)LaΑ1O3 facets. These steps provide aligned and enhanced nucleation sites for RBCO.…”

The growth of (RE)1Βa2Cu3O7-δ (RE: Y, Nd) fflms on NdGaO3 and SrΤiO3 substrates by ion-beam and dc-/rf-magnetron sputter deposition is discussed in the framework of growth kinetics, oxygen exchange, epitaxial relations, substrate crystal orientation, in-plane coherence, vicinal substrate cuts, overgrowth on steps, superconductor/insulator combinations, and patterning by ion-beam etching. Tle process conditions for ion-beam and magnetron sputter deposition are briefly outlined.
