Outline of Final Research Achievements

Thermal stability and degradation of DLC thin films and ultra-thin liquid lubricant films on conventional magnetic disk surfaces due to rapid laser heating were investigated, using Raman microscope. The effects of high temperature caused by laser heating and inert gas environments were elucidated experimentally. In addition, we developed a novel plasmon sensor and it became possible to evaluate more detailed Raman spectroscopy analysis using our novel plasmon sensors, by increasing the intensity of Raman scattered light.
