| Outline of Final Research Achievements |
Infrared multiple-angle incidence resolution spectrometry (MAIRS) has attracted much attention in recent years as a spectroscopic tool for structural analysis of functional organic thin films. While this method can be easily measured using commercially available FT-IR spectrometers, it has the experimental limitation of using only substrates transparent to infrared light because the measurements are performed with transmission optical systems. This makes it difficult to directly measure practical thin-film devices that incorporate glass substrates and metal electrodes. To overcome these difficulties, a new MAIRS technique was developed in this research.
