Abstract

We report the first growth of InSb and GaAs epilayers upon a garnet (YIG = Y3Fe5O12) epilayer. The YIG was deposited using liquid phase epitaxy on a garnet (GGG = Gd3Ga5O12) substrate oriented in the [111] direction. The growth of the GaAs was carried out using laser ablation and no superlattice was used to buffer the lattice mismatch between YIG and GaAs. The growth of InSb was done by low-pressure metalorganic chemical vapor deposition. From x-ray diffraction analysis it was found that the GaAs and InSb were both (110) monocrystalline epitaxial layers.
