The Au ultra-fine films were gown by MBE or magnetron sputtering on Al2O3 or MgO single crystals which were annealed at 1000 degrees C to obtain smooth surfaces with a step-terrace structure. A one-dimensional alignment of Au particles was partially observed around the steps on Al2O3(0001), (1012) surfaces at about 600 degrees C. On the other hand, Au ultra-fine films were also deposited by magnetron sputtering on MgO(100). The two processes were proceeded to obtain C-60 monolayers on the above Au films. Only C-60 molecules adsorbed on Au remained and the others were re-evaporated by annealing at 350 degrees C. By this re-evaporation method the nanostructured C-60 monolayers were fabricated. In addition self-assembly monolayers of a C-60 derivative, C-60-O-C8SH, (C-60-SAM) were synthesized on the Au/MgO by soaking in benzene solution of the C-60 derivative. The C-60-SAM was obtained only along the step edges. In the case of C-60-SAM on ultra-fine Au films/MgO several samples showed the resistivity anomalies at 150-250 K accompanying with specific deviation from metallic linear dependences on temperature.
