摘要
c-axis oriented YBa2Cu3O7-y (Y123) thick films were grown on NdGaO3(110) single crystalline substrates by liquid phase epitaxy (LPE). The growth mode of the film changes from a multi-nucleation growth to a spiral-step growth. The growth of the initial stage occurs due to the local supersaturation at the growth interface by the temperature difference between the substrate and the surface of the melt and the later stage growth is driven by the supersaturation from the transport of the solute through convection of the melt. The change of growth mode is also described as the change from the transient mode LPE (TMLE) growth to the steady state growth.
