In recent years, limitations of downscaling in silicon based device technologies have come to be well recognized, and alternatives based on new operation principles and/or novel materials are being extensively explored. It is also well recognized that developments of such alternatives have to be started from a few of tens nanometer scale in device sizes. Hence evaluations of materials with corresponding spatial resolution are required. Our research group utilized scanning tunneling microscopy as a tool to elucidate the photo-electronic properties of the materials in atomic scale. This study intends to develop a new vibrational spectroscopic method with the nanometer-scale resolution and to apply this method to actual device evaluations. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.
