Abstract
The growth of rubrene thin films thermally evaporated under ultraβhigh vacuum (UHV) on SiO~2~ has been investigated by combining atomic force microscopy (AFM), scanning electron microscopy (SEM), and polarized optical microscopy (POM) techniques. A mode of thin film growth in which an amorphous continuous holy film first covers the substrate, and acts afterwards as a template for the nucleation of polycrystalline rubrene spherulites, has been identified. Additionally, rubrene oneβdimensional structures have been observed with a catalystβfree growth process. (Β© 2007 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)

The fabrication of MOS structures using an improved wet anodisation technique at low temperature, together with electrical and interfacial properties of the grown films are discussed. The thin films, of the order of 300 A thick, grown by anodic oxidation, have characteristics comparable with those o
