ABSTRACT
We demonstrate a ternary (La[sub x]Y[sub 1-x])[sub 2]O[sub 3] thin-film oxide that can be grown epitaxially on Si(111) substrates with a lattice constant that can be matched to twice the lattice constant of silicon. We further show that silicon can then be deposited epitaxially (though with a high defect density) on this oxide such that epitaxial silicon/oxide/silicon structures may be grown. We discuss the microstructural relationships and the growth modes for the oxide on silicon and silicon on oxide growths. © 2002 American Institute of Physics.
