Here we report the expansion of the Ga 2 O 3 solubility range in ZnO films grown by MOCVD on single-crystal substrates due to the epitaxial stabilization contribution. The epitaxial relations were characterized for ZnO and a broad spectrum of the substrates including c-and r-Al 2 O 3 , (111) ZrO 2 (Y 2 O 3 ), (111) SrTiO 3 , (111) Gd 3 Ga 5 O 12 , (111) MgO, (111) MgAl 2 O 4 . First, the deposition kinetics was measured in the range 300-800 • C using Zn(acac) 2 and Ga(acac) 3 , where acac = the acetylacetonat…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
