| 研究開始時の研究の概要 |
The effect of boundary curvature on the wrinkling of a thin suspended film, such as eardrums and plant leaves, is poorly understood. To captures the main physical ingredients that explain this effect, methods for the microfabrication of suspended diamond films that in a controlled way mimic such systems will be developed together with a theoretical model. The final goal is to advance our fundamental understanding of wrinkling phenomena but also provide a foundation for advancing various applications, such as the design of devices with functional wrinkles, and to understand natural phenomena.

| 研究実績の概要 |
We could fabricate wrinkled structures of arbitrary shape starting from nanocrystalline diamond films deposited on glass substrates. This was done using direct femtosecond laser writing and wet etching. With laser writing, patterns were made in the films, and wet etching was carried out to etch the substrate partially. The model for describing the wrinkling patterns is under development.
We found that laser writing can produce nanochannels between the glass substrate and the diamond film. Consequently, we fabricated a nanofluidic device based on our etching technology to demonstrate that the nanochannels can conduct water. The film patterning mechanism was investigated in depth. Our work has been published in the journal Carbon, and a patent application has been filed.
