Formation of SiH bonds when SiO is deposited on alumina

Abstract
Thin films of silicon monoxide have been deposited on alumina surfaces and examined by inelastic electron tunnelingspectroscopy. A strong absorption peak at 2210 cm−1 reveals the formation of SiH bonds in the presence of trace amounts of water. It is inferred that a reaction between SiO and –OH groups to yield SiH bonds is catalyzed by the alumina surface.
