    • Abstract

       

      Scanning tunneling microscopy of C70 films deposited on HOPG and gold substrates has been carried out to investigate the 2D packing, defects and disorder. Besides providing direct evidence for orientational disorder, high resolution images showing the carbon skeleton as well as the molecular arrangement in a solid solution of C70 and C60 are presented. Tunneling conductance measurements indicate a small gap in the C70 film deposited on HOPG substrate.
