摘要
Spreading droplets of nonvolatile liquids show striking steplike thickness profiles, revealing a smectic order induced by the solid surface. The dynamics of growth of the successive layers has been studied experimentally and compared with a numerical study using Monte Carlo simulation. The steplike profiles, the diffusive behavior observed at the early stages of spreading, and the slowing-down occurring at long times due to the finite volume of the droplet are satisfactorily accounted for.
