概要	We investigated the charge transport characteristics of alkanemonothiol (CnH2n+1SH, n: number of carbons) molecular junctions by means of transition voltage spectroscopy (TVS) based on the observations of the interface electronic structures. The results were consistently explained by the Au-S bond being responsible for Vmin at the negative bias. In addition, another interface state was suggested to be responsible for Vmin at the positive bias. The effects of the interface electronic structures besides the apparent barrier height should be considered to understand TVS of molecular junctions with wide energy gap molecules.
