Aebi, Philipp 2012-05-03 Since more than twenty years it is known that deposition of Ag onto Si(111)–(7 × 7) leads under certain conditions to the formation of so-called “ring-like” clusters, that are particularly stable among small clusters. In order to resolve their still unknown atomic structure, we performed voltage dependent scanning tunneling microscopy (STM) measurements providing interesting information about the electronic properties of clusters which are linked with their atomic structure. Based on a structural model of Au cluster on Si(111)–(7 × 7) and our STM images, we propose an atomic arrangement for the two most stable Ag “ring-like” clusters. application/pdf https://folia.unifr.ch/global/documents/302458 https://folia.unifr.ch/documents/302458/files/aeb_stm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.susc.2012.05.002 info:eu-repo/semantics/openAccess License undefined Surface Science. - 2012, vol. 606, no. 23-24, p. 1755-1759 Clusters Self organization Silicon Silver Structural model Scanning tunneling microscopy info:eu-repo/classification/udc/53 Scanning tunneling microscopy at multiple voltage biases of stable “ring-like” Ag clusters on Si(111)–(7 × 7) http://purl.org/coar/resource_type/c_6501
