内容摘要Abstract：

The unique characteristics of small transition metal and coinage metal clusters continue to raise interest in the scientific community, while their unique functional properties are directing them toward novel applications. From a fundamental point of view small clusters of just a few atoms constitute ideal model systems of complex materials, in particular concerning the interplay between geometry and electronic structure that shapes their quantum properties. Nowadays, small metal clusters produced in the gas phase and embedded in various scaffolds are readily available for advanced studies.

In this talk I will present an overview of recent studies on small clusters, focusing on cobalt, gold and their alloys. A selection of experiments, both on beams of clusters in the gas phase and after deposition on surfaces, will be presented. Particular focus will be on magnetism, optical properties, and chemical reactivity.

个人简介(About the speaker):

Peter Lievens is professor in experimental physics in the Department of Physics and Astronomy of the KU Leuven. He obtained his PhD in 1991 at the KU Leuven in nuclear physics, on laser spectroscopy studies of ground state properties of short-lived strontium nuclei. He obtained tenure in 2001 and is full professor since 2007. From 2009 till 2017 he was Dean of the Faculty of Science. Since August 2017 he is KU Leuven Vice rector responsible for International Policy, LERU, and Alumni Policy.

His research activities focus on physical and chemical properties of nanoclusters in the gas phase, individual clusters on surfaces, cluster assembled thin films, and low-dimensional systems. He published over 260 papers in international peer-reviewed journals and presented over 50 invited lectures at international conferences, workshops, and universities. He has been supervisor of over 30 PhD students.
