| Outline of Final Research Achievements |
From recent research, it has been gradually understood that the uniform thin film on the large-area substrate and the high-quality thin film controlled at the atomic layer level are obtained by “super-migration” caused by Leidenfrost state droplet in mist CVD. The technique will be promising for the functional thin film fabrication on the three-dimensional object. Thus, the behavior analysis of the droplet with a diameter of a few micrometers at Leidenfrost state is a main focus in this study.
The observation of the droplet with a diameter of a few micrometers is difficult because it is not stable under atmospheric pressure and is easily moved by a heat disturbance. Then, prototype system of special-specification was designed and was installed into the measurement system. Finally, the micrometer droplet with a velocity of a few meters was successfully observed with the system.
