Abstract :
Organic monolayers of dotriacontane and tetracosanoic acid physisorbed on graphite have been studied by scanning tunneling microscopy at the liquid-solid interface. A high degree of two-dimensional ordering appeared for both the organic compounds observed : the molecules were arranged on graphite in stripelike lamellae of various shape and length. Experimental conditions for high contrast imaging are discussed.
