Abstract
Monolayers of the organic donor OMTTF (octamethylene-tetrathiafulvalene) we re grown on a Ag(100) substrate and on the iodine c(2x2) superstructure on Ag(100) by organic molecular beam deposition (OMBD) under ultra high vacuum (UHV) conditions. The films were characterized by low energy electron diff raction (LEED) and scanning tunneling microscopy (STM). In the monolayer re gime the molecules grow on both substrates in an ordered structure. By comp aring the degree of long-range order and the geometrical structure observed on Ag and on iodine with that of OMTTF-TCNQ we discuss the interplay betwe en the different interactions and long-range order in epitaxial growth.
