Abstract

A new surface phase is found in liquid normal-alkanes. X-ray and surface tension measurements show the formation of a crystalline monolayer on the surface of the liquid at temperatures up to 3°C above the bulk solidification temperature, T_f. The molecules in the monolayer are hexagonally packed and oriented normal to the surface. A single solid monolayer persists down to T_f, thus exhibiting a very limited partial wetting. The new surface phase is obtained only for chain lengths 14<n≤50. Its vanishing for n≤14 is interpreted as a possible transition from surface freezing to surface melting behaviour. The measurements are satisfactory accounted for within a simple theory based on surface energy cosiderations.
