Abstract
- International audience; Wetting of ìm-sized Pb droplets on thin polycrystalline films of decagonal Al13Co4 and cubic crystalline AlCo phases is reported. The sample preparation is crucial to have Pb droplets lying on a clean surface. Decagonal and cubic films were prepared under high vacuum conditions, by sequential deposition and annealing of specific stackings of Al and Co layers of nanometric thicknesses. A 300nm-thick Pb slab was then deposited on the top of the films. Dewetting experiments were performed in situ in a scanning Auger microprobe where the surface chemistry can be monitored: the Pb slab dewetts into droplets. The wetting of Pb on both substrates was found to be similar with contact angles around 45°.
