Description:

(abstract)

We investigated the effect of mask materials on the epitaxial lateral overgrowth (ELO) characteristics of alpha-Ga2O3 and developed an ELO technique that can markedly suppress abnormal growth and cracking to enable long-term growth on a wide mask, which is necessary to effectively improve the crystal quality. alpha-Ga2O3 islands with a diameter as large as approximately 25 um were grown by the developed ELO technique using polycrystalline kappa-Ga2O3. Transmission electron microscopy observation did not detect dislocations in the outermost part of the islands.
