Scanning Tunneling Microscopy (STM) reveals details down to the molecular and submolecular scale. This paper presents STM images taken under solution of three well known organic compounds deposited on highly oriented pyrolitic graphite. Dotriacontane, stearic acid and tetracosanoic acid showed to form highly organized monolayers that have a characteristic two-dimensional structure. Conditions for high resolution and optimal contrast are discussed. Different monolayer packing for stearic acid in correspondence of two concentration values are also reported.

Abstract
Scanning Tunneling Microscopy (STM) reveals details down to the molecular and submolecular scale. This paper presents STM images taken under solution of three well known organic compounds deposited on highly oriented pyrolitic graphite. Dotriacontane, stearic acid and tetracosanoic acid showed to form highly organized monolayers that have a characteristic two-dimensional structure. Conditions for high resolution and optimal contrast are discussed. Different monolayer packing for stearic acid in correspondence of two concentration values are also reported.
