The application of scanning tunneling microscopy and spectroscopy (STM/STS) to the study of structural and electronic properties of organic/inorganic systems is presented here. The investigation of PTCDA (3,4,9,10, perylene tetracarboxylic dianhydride, C 24 O 6 H 8 ) on semiconductor or metal surfaces by means of STM/STS shows a wide diversity of results indicating a complex behavior of the PTCDA molecules. It has been found that the surface reactivity highly influences the PTCDA adsorption and growth properties. The degree of molecule–surface interaction can lead to randomly chemisorbed molecules on highly reactive substrates, to one‐dimensional row formation on moderately reactive surfaces and well‐ordered overlayers in the case of physisorbed PTCDA molecules on weakly reactive surfaces.
