Popis:	The growth of silver on UHV cleaved MgO(001) at various temperatures is in situ studied with IR spectroscopy followed by ex situ AFM. In the whole substrate-temperature range for silver deposition used in this study (from about 70 K to 500 K) island formation is observed. Continuous films at higher thicknesses may have metallic properties close to typical silver-bulk data. Differences in the IR optical properties are clearly related to the film structure. The results from an IR spectral analysis of transmittance data with a Drude-type model are corroborated by IR spectral features of CO adsorbed on the films, and by AFM pictures.
