Claim 27:
28. A method, comprising:
(1) inducing formation of a first vapor from a first target comprising a lithium-containing material and formation of a second vapor from a second target comprising lithium and nitrogen such that the first vapor and the second vapor are deposited on a surface, resulting in the formation of a thin film on the surface, the thin film comprising a multilayer film comprising alternating layers of a first layer comprising a lithium-containing material and a second layer comprising lithium and nitrogen, and
(2) removing a majority of nitrogen in the multilayer film and/or merging the alternating layers,
wherein:
the formation of the first vapor and the formation of the second vapor are induced sequentially,
at least a portion of the formation of the first vapor and at least a portion of the formation of the second vapor occur under vacuum conditions.
