STABILITY OF A DEPOSITED LIQUID CLUSTER

The fragmentation of silver liquid clusters deposited onto a silicon surface is observed after heating the clusters to 1073 K and subsequently annealing with the exposition time 3 min. This contradicts macroscopic models of a liquid drop deposited on a surface if we are based on critical parameters of bulk silver. Some versions are analyzed that are based on cluster properties and may explain the phenomenon of cluster fragmentation. An experiment is suggested for clarifying the nature of the cluster fragmentation phenomenon and cluster critical phenomena.
