摘要：
We present a study of the growth of silver nanoparticles or clusters on a TiO2(110) substrate in ultra-high vacuum. The growth is monitored in situ by ion and neutral scattering spectroscopy using He+ scattering and Auger spectroscopy. The scattering measurements show that only part of the surface is covered by Ag suggesting formation of clusters. Additionally an ex-situ study was performed by scanning electron microscopy and atomic force microscopy to determine the size distribution of these clusters. The average size distributions were found to range from about 5 to about 20 nm as a function of the evaporation flux. At the higher evaporation flux we observe formation of the smaller sized clusters. (C) 2003 Elsevier B.V. All rights reserved.
