Abstract:
Spatially resolved images of an individual C$_{60}$F$_{36}$
fluorofullerene molecules on Si(111)–$7 \times 7$ surface have been
obtained by means of scanning tunneling microscopy/spectroscopy
(STM/STS). The presence of isomers with different symmetry ($T$,
$C_3$, $C_1$) has been revealed in STM investigation of initial
adsorption stage of C$_{60}$F$_{36}$ on silicon surface
Si(111)–$(7\times7)$. 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 C$_{60}$F$_{36}$
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
C$_{60}$F$_{36}$ molecules adsorption on Si(111)–$(7\times7)$ surface
was stable and kept equilibrium configuration during several hours.
