N2 - Reactions of thin films of clean lithium with freshly cleaved silica surfaces have been characterized by X-ray photoelectron spectroscopy (XPS). Reaction rates (near room temperature) are low enough that spectroscopic analysis is possible during the entire course of the reaction. The major product of the reaction is composed of oxidized lithium, a metasilicate (SiO2-3) species, and a unique form of reduced Si, possibly a lithium-rich alloy phase. For confined regions, where the lithium concentration can be made extremely high (as in these thin film depositions) the reaction with the active metal gives a product distribution not predicted by previous thermodynamic arguments.
