P‐137: Versatile shape nanostructure fabrication technique using low power continuous wave laser

In this study, the periodic nanostructures of various shapes were fabricated using a low‐cost, low‐power continuous wave laser. The nanostructures can be easily fabricated with a low‐cost and simple process using a laser interference lithography technology. In addition, we demonstrated that various shapes such as spherical, hemispherical, and wavy can be easily controlled by adjusting the surface energy of the substrate and process parameters.
