Auger spectroscopy of a fullerite film on an iridium surface
Rut'kov E. V. , Tontegode A. Ya. , Grushko Yu. S.
A technique has been developed for producing a flux of C^o molecules in ultrahigh vacuum and has been used to grow fullerite films on iridium. The Auger spectrum of carbon from the fullerite has been obtained at high resolution (Δ.Ε/Ε % 0.1%). This spectrum has a characteristic shape which is different from the spectra of diamond, graphite single crystals, polycrystalline graphite, metal carbides, and SiC. The Сбо molecules begin to desorb from the fullerite at > 600 K, and from the iridium at > 900 K; the flux depends weakly on T. At > 1200 К the molecules effectively decay in the adsorbed film on the Ir, forming graphite.
