| Outline of Final Research Achievements |
To improve environmental stability of Ag thin films, we introduced several kinds of organic molecules, such as 3-mercaptopropyltrimethoxysilane (MPTMS), 1-dodecanethiol (1-DT), as a surface layer or an interface layer with a glass substrate. The environmental test was carried out at 40 °C and 90 RH% for mainly 7 days. The surface roughness, sheet resistance, and optical transmittance of the Ag films with the organic monolayers showed less change than that of single-layer Ag films. As a result, the organic monolayers protect the Ag thin film. The effect as a surface layer was compared among molecules, and it was found that 1-dodecanethiol (1-DT) and 1-octadodecanethiol (1-ODT) were highly effective. To use a flexible substrate, we have reviewed a process to prepare the monolayer, and we have found ethanol solvent is preferable.
