Abstract
Molecular monolayer structure investigations have been performed by Sc anning Tunneling Microscopy (STM) on self-assembled systems made of do triacontane, stearic acid, tetracosanoic acid and octadecylmercaptane adsorbed on graphite. High-resolution voltage-bias dependent STM image s have been obtained and conditions for optimal image contrast are dis cussed. A correction procedure to minimize scanning-induced geometrica l distortion has been successfully applied on dotriacontane and octade cylmercaptane images.
