EXPERIMENTAL-STUDY OF SCALING PROPERTIES AND ROUGHING MECHANISMS IN C-60-AG THIN-FILMS

Surface morphologies and microstructures of C-60/Ag composite films we re studied by atomic force microscope (AFM) and transmission electron microscope (TEM). The surface roughness depended on the substrate temp erature, and the transition of surface morphology of rough-->smooth--> rough was observed when the substrate temperature increased from - 50 to 120 degrees C. Although the rms values are similar, the scaling pro perties of the thermal roughing and the kinetic roughing surfaces are quite different. The relations between the scaling properties, microst ructures and roughing mechanisms are discussed based on the AFM and TE M results.
