The photoresponse ofpassivatingfilms grown on tin in slightly alkalinesolutions has beenstudied under both galvanostatic and potentiostatic conditions. The response of films growing under galvanostatic conditions was used to determine the nature and magnitude of their deviation from stoichiometry, a
Recent infrared and Raman spectroscopic studies of various tungsten oxide films concluded either the formation of \(\mathrm{W}=\mathrm{O}\) terminal bonds or the transformation of such bonds into \(\mathrm{W}-\mathrm{OH}\) groups upon proton insertion. The infrared transmission and reflection spectr
