STM/STS study of C60F36 molecules adsorption on 7× 7-Si(111) surface
Spatially resolved images of an individual  C60F36 fluorofullerene molecules on Si(111)-7 × 7 surface have been obtained by means of scanning tunneling microscopy/spectroscopy (STM/STS). The presence of isomers with different symmetry (T, C3, C1) has been revealed in STM investigation of initial adsorption stage of  C60F36 on silicon surface Si(111)-(7×7). The adsorbed fluorofullerene molecule can occupy any adsorption site of silicon surface (corner site, faulted half, unfaulted half) that indicates for strong molecule-substrate interaction. The HOMO-LUMO gap of the adsorbed  C60F36 molecules have been estimated from current image tunneling spectroscopy (CITS) and z(V) with engaged feedback measurements. The value of HOMO-LUMO gap observed experimentally was 3 eV. The  C60F36 molecules adsorption on Si(111)-(7×7) surface was stable and kept equilibrium configuration during several hours.
