High <i>I</i>$_{\textrm{c}}$, YBa$_{\textrm{2}}$Cu$_{\textrm{3}}$O$_{\textrm{7−<i>x</i>}}}$ films grown at very high rates by liquid assisted growth incorporating lightly Au-doped SrTiO$_{\textrm{3}}$ buffers [pdf]Paper  doi  abstract   bibtex   
YBa$_{\textrm{2}}$Cu$_{\textrm{3}}$O$_{\textrm{7−x}}}$ (YBCO) thick films were grown by hybrid liquid phase epitaxy (HLPE) on (001) SrTiO$_{\textrm{3}}$ (STO) substrates. In the presence of a 100 nm thick, 5 mol% Au-doped STO buffer, self-field critical current densities, J$_{\textrm{c}}$$^{\textrm{sf}}$, at 77 K of ~2.4 MA cm$^{\textrm{−2}}$ and critical currents, I$_{\textrm{c}}$$^{\textrm{sf}}$, up to 700 A (cm-width)$^{\textrm{−1}}$ were achieved. The J$_{\textrm{c}}$ value is virtually independent of thickness and the growth rates are very high (~1 µm min$^{\textrm{−1}}$). From transmission electron microscopy (TEM), Y$_{\textrm{2}}$O$_{\textrm{3}}$ nanocloud extended defects (~100 nm in size) were identified as the pinning defects in the films. Enhanced random pinning was induced by the presence of Au in the buffer.
