摘要：
The evaporation of n-hexadecane from highly oriented pyrolytic graphite (HOPG) has been investigated using tapping mode atomic force microscopy. Four evaporation times of 5, 10, 15, and 25 min have been studied. The same gross features are observed for all evaporation times, namely two types of isolated features located on the terraces and continuous features associated with steps on the graphite surface. Extensive measurements have been performed on the observed features allowing a detailed comparison between evaporation times;Models describing the molecular orientations within the features are proposed.
