    • Although we checked desorption spectra for several mass numbers around 234 amu, no desorption features were detected for neither mass numbers.

    • Since a nozzle was used for the C6 gas exposure, the local pressure at the sample position is higher than the value measured by the pressure gauge. So, the estimated sticking coefficient is a maximum value.

    • When the tip was approached very closely to the surface with an extremely low tunneling gap impedance (typically 20 MΩ), the (1 × 1) atomic arrangement of Au(111) was observed.

    • 2 unit: J. F. Nagle, Faraday Discuss. Chem. Soc. 81, 151 (1986)], the estimated intermolecular interaction between the nearest neighbor sites is close to zero. This might be explained by cancellation due to an electrostatic repulsive interaction between the head sulfur atoms since the sulfur atom of a surface thiolate on gold has some negative charges

    • [V. P. Zadanov, Surf. Sci. ibid. 123, 106 (1982)]. The attractive interaction due to the van der Waals interaction between adjacent C6-alkyl-chains in the hexagonal close-packed arrangement is 3.3 kcal/mol per nearest-neighbor-site pair. This value will be reduced at desorption temperatures due to disordering of the arrangement.
