Claims23
A process for making a crystalline film on a substrate comprising applying to the substrate amorphous nanoparticles and heating to cause the constituents of the amorphous nanoparticles to nucleate and grow on the substrate to form a crystalline film.
A process for forming a stable dispersion of amorphous nanoparticles comprising heating a mixture of a non-reactive solvent and organic salts of one or more metals to a temperature sufficient to cause the one or more organic metal salts to decompose into amorphous nanoparticles that are stably dispersed in the non-reactive solvent.
A process for forming a metal oxide epitaxial film on a substrate comprising heating a mixture of a non-reactive solvent and at least one organometallic salt to decompose the at least one organometallic salt into amorphous nanoparticles that are stably dispersed in the non-reactive solvent, applying the dispersion of amorphous nanoparticles to the substrate that exhibits a crystallographic structure, and heating to cause the metal constituents of the amorphous nanoparticles to nucleate and grow on the substrate to form an epitaxial crystalline film.
