Low temperature synthesis of LiGaO2 using lithium nitride

Abstract

A novel synthetic route to the preparation of lithium metagallate (LiGaO2) crystals from Ga2O3 and Li 3N under condition milder than conventional methods has been explored. We have found that a reaction of Ga2O3 and Li3N at temperatures ranging from 500°C and 800°C in chloride fluxes yields formation of LiGaO2 single crystals. This technique has applicability to the synthesis of LiGaO2 crystals, which are known to be suitable substrates for epitaxial growth of GaN.
