In order to realize novel useful functions in micro and nanodevices or to considerably improve their performance, it is important to tailor the nanomorphology of various materials. Through the introduction of bottom-up processes as well as modern top-down processes, devices with advanced new structures can be designed and fabricated. We are developing a new technique to control material nanomorphologies and are investigating their applications.

We focus our attention on physical self-assembly induced by the “Dynamic Oblique Deposition” (DOD) technique and attempt to realize complex 3D nanostructures. We are also interested in their shape-related useful properties from the viewpoint of application to optical elements, sensing using various local enhancement effects, and photo- and thermo-acoustic phenomena. In addition, we aim at developing novel techniques to control nanomorphology by clarifying the elementary atomic processes during growth of nanostructures.
