Résumé

L'influence de la modification d'une pointe STM sur le contraste observé dans l'image a été investiquée. Cette technique révolutionnaire est appliquée à l'identification de l'organisation moléculaire au sein de monocouches auto-assemblées (SAMs) d'estrs de cire. De plus, la différence de contraste observé lors de l'utilisation de différentes modifications de pointe, a permis de mettre en évidence la position et l'orientation du groupement ester. L'application de ce processus à l'étude de couches d'acides gras démontre sa transposabilité à d'autres composés.
