    • Although the HOMO-LUMO gap of alkyl chain type molecules has been reported (see ref 21), there is no experimental data on the HOMO-LUMO gap for the Au/alkanethiol SAM/Au system. The commonly used HOMO-LUMO gap of alkanethiol is 8 eV.

    • Wold and Frisbie (ref 7) have reported a transition of the slope from -0.83 to -7.5 when the loading force becomes larger than 70 nN on the alkanethiol-coated Au substrate at which an abrupt change of SAM structure was assumed.
