摘要

Epitaxial layers of NdAl_3(BO_3)_4 (NAB) and YAl_3(BO_3)_4〈Yb〉 (YAB〈Yb〉) containing up to 10 at % Yb have been grown by liquid-phase epitaxy on YAB substrates. Their growth kinetics have been studied at relative supersaturations of the high-temperature solution from 2 × 10~(-2) to 16 × 10~(-2). The ytterbium concentration in YAB〈Yb〉 has been shown to vary little during the epitaxial process. Near the edges of the substrate, the surface morphology of the layers is complicated by vicinals, which have a spiral form in the case of YAB〈Yb〉. On {1011} YAB substrates, homogeneous single-crystal NAB films have been grown.
