Abstract

Single-crystalline La3Ga5.5Ta0.5O14 and La3Ga5.5Nb0.5O14 films were grown by liquid phase epitaxy (LPE) for the first time. Crack-free thin films up to 1.5 × 1.5 cm2 were obtained from a PbO-based flux on X-,Y-, and Z-oriented substrates, by homoepitaxy. Characterization was done by AFM, SEM/EDAX, XRD and optical microscopy. The morphology of X- and Y-oriented LGT films show a similar growth habit as previously found for LGS LPE films. X-LGT films are extremely flat over macroscopic dimensions. On Y-oriented films, (macro)steps and facets are formed, and growth hillocks and spirals were observed on Z-oriented LGN films. © 2002 Elsevier Science B.V. All rights reserved.
