The present invention provides an apparatus and method for the synthesis and identification of composite metal oxides formed as combinatorial variables by molecular beam epitaxy of a substrate, and the results of such synthesis, i.e. stable or metastable composite oxides, multilayers, and superlattices. To a combinatorial array (or library) of samples. The site-addressable combinatorial library of complex oxides having thermally labile structures is characterized by the formula (A 1 ) × 1 (A 2 ) × 2 ... Thermally stable or metastable with (A n ) xn O y , wherein at least one of the elemental components A i is a metal, x i , y is an integer or fraction containing 0 and n = 2 to 20 Including an oxide, the stoichiometry or structure of the oxide changes in a systematic and known manner in at least one elemental component as it progresses between one side region and the other side region in a pair of opposing side regions. Also disclosed is the use of a library to identify complex oxides having desired properties, ie high temperature superconductivity. |
