Abstract
A dielectric thin film material and method of preparation in which precursors are provided to form barium strontium titanate with lanthanum (La) added as a dopant. The precursors and La dopant are mixed with a solvent forming a solution which is deposited on a substrate to form a continuous film composition. In various embodiments, the dielectric thin film has a composition of (1-y)Ba Sr TiO −(y)La, where y=0 to 10-mol. The thin film material has dielectric and insulating properties suitable for tunable microwave applications.
