The invention relates to a nanostructured BaTiO.sub.3 film, plate or array that has from 1,000 to 10,000 times the storage capacity of conventional capacitors. The barium titanates are of the formula Ba.sub.a Ti.sub.b O.sub.c wherein a and b are independently between 0.75 and 1.25 and c is 2.5 to about 5.0. The barium titanates may further be doped with a material, "M", selected from Au, is Au, Cu, Ni.sub.3 Al, Ru or InSn. The resulting titanate may be represented by the formula M.sub.d Ba.sub.a Ti.sub.b O.sub.c wherein d is about 0.01 to 0.25, a is about 0.75 to about 1.25, b is about 0.75 to about 1.25 and c is about 2.5 to about 5.0. X-ray diffraction results illustrate that the crystal structure of the thin films changed from predominantly cubic to tetragonal phase and crystallite size increased with increasing concentration of "M".

La invención se relaciona con a nanostructured la película BaTiO.sub.3, la placa o el arsenal que tienen a partir 1.000 a 10.000 veces la memoria de condensadores convencionales. Los titanates del bario están del fórmula Ba.sub.a Ti.sub.b O.sub.c en donde a y b son independientemente entre 0.75 y 1.25 y c es 2.5 a cerca de 5.0. Los titanates del bario se pueden dopar más lejos con un material, "M", seleccionado del au, son au, Cu, el al Ni.sub.3, Ru o InSn. El titanate que resulta se puede representar por el fórmula M.sub.d Ba.sub.a Ti.sub.b O.sub.c en donde d es cerca de 0.01 a 0.25, a es cerca de 0.75 a cerca de 1.25, b es cerca de 0.75 a cerca de 1.25 y c es cerca de 2.5 a cerca de 5.0. Los resultados de la difracción de radiografía ilustran que la estructura cristalina de las películas finas cambiantes de predominante cúbico a la fase y al tamaño tetragonales del cristalito aumentó con el aumento de la concentración de "M".
