2014 2014-07-25T10:54:25Z Luo, Yuan Luo, Yuan "Paralleldeposition" von Massenselektierten Clustern terms-of-use A new size-selected cluster deposition technique referred to as "paralleldeposition" is presented. An ion beam composed of multi-sized positively charged molybdenum and gold clusters was spatially resolved into individual Cluster sizes by utilizing a Wien filter. The beams containing only a single mass were subsequently deposited on a SiO<sub>2</sub>/Si (100) substrate, giving rise to well-separated spots containing only one cluster size. Experimental techniques employed to investigate this novel method include resolution of the ion beams with a Channeltron detector in the gas-phase and the investigation of the deposited spots by conventional and monochromatic imaging XPS. It is found that “paralleldeposited” Au<sub>n</sub> (n = 5, 6, 7 and 8) clusters exhibited even-odd behavior in their reactivity toward oxidation, thus, reproducing a well-acclaimed result obtained before. This shows the validity of the approach of "paralleldeposition" and demonstrates the potential of this new technique in investigating size-dependent properties of deposited clusters.
