Abstract

Fullerene C₆₀ and C₇₀ mixture films on Ag(100) have been studied with scanning tunneling microscopy (STM) and low energy electron diffraction (LEED). In contrast to the recently found aperiodic incommensurate "(111)" phase of C₆₀ on Ag(100), C₇₀ formed a commensurate c(6 × 4) structure. Co-deposited C₆₀/C ₇₀ mixture layers were examined as a function of controlled C ₆₀/C₇₀ ratio. LEED showed that overall film symmetry evolved from "(111)" to c(6 × 4) as C₆₀ density increased. In contrast, STM revealed that C₆₀ and C₇₀ distributions were highly non-uniform, with many prominent unidirectional wavy bright lines due to local C₆₀ aggregation.
