COMPOSITE INCLUDING A LAYER OF A III-V COMPOUND AND A LAYER OF RARE EARTHS, PROCESS FOR ITS PRODUCTION AND ITS APPLICATION

摘要

a composite material comprising a layer of a layer composed of a iii - v and rare earth pnictide, manufacturing process and application of the present invention relates to a composite material.the material comprises at least one layer of a iii-v compound layer and a b layer on the epitaxy of iii-v compounds.the epitaxy layer with the molecular formula trpc where r is selected from the group of rare earths (scandium, yttrium, lanthanide, preferably lanthanum.and their mixtures; and cp is selected from among the elements of the column v of the periodic table of elements and mixtures thereof, and by the fact that when cp contains arsenicthe compound is at least one trpc ternary compound. the application for the electronics industry. figure 1
