| Outline of Final Research Achievements |
1) The micro fluid device was modified for automatic synthesis operation. 2) By the use of cobalt phthalocyanine/fullerene nano particle, high external quantum efficiency to be unity was observed for the volatile compound mineralization especially for the initial time of light illumination of weak visible light of milli watt/cm2. 3) We have not obtained direct observation of potential structure by the use of Kelvin probe microscopy. 4) But, for the step like p-n junction materials, repeatable deep potential structure at the p-n junction was observed. 5) Furthermore, by the array of the step structure, increased at less bias potential photo anode current. It means the micro deep potential can be applied for macroscopic phenomena.
