“…Though there are plenty of theoretical calculations available for size-selected clusters in the gas phase [227,233,234,235] and even results on surfaces [236,11], experimental investigation (by means of local methods, e.g. STM or TEM) on the local structure have been (recently) reported [229,237,238,95,239,211] and are heavily dependent on cluster and support material as well the experimental conditions. 10 Further, with larger clusters support effects become more important along with an increasing number of structural isomers.…”
