The electrical resistivity of nanoporous gold (NPG) modified with thiol self-assembled monolayers (SAMs) has been measured at 298K using a four-probe method. We found that the adsorption of thiol SAMs increases the electrical resistivity of NPG by up to 22.2%. Dependence of the electrical resistivity on the atmosphere (air or water) was also observed in SAMs-modified NPG, suggesting that the electronic...
The effect of water adsorption on the electrical resistivity of nanoporous gold (NPG) thin films, as well as flat gold (FG) with no nanoporosity, has been examined. Both NPG and FG thin films showed higher electrical resistivity in water than in air; however, the difference between the electrical resistivity of NPG in water and in air was quite large. The first-principles calculations suggest that...
