Outline of Final Research Achievements

The film formation based on the ultrasonic mist deposition has advantages of low energy and low cost processing compared with conventional processes. We have studied the mist deposition method where a crystalline nanoparticle-containing solution was deposited on a substrate to form a crystalline film at a low temperature, the surface micro-textures of the mist-deposited films, and the electrical and the optical properties. A new method to control the surface texturing based on a hydrophilic-hydrophobic micro-pattern prepared by laser direct writing was developed. The film formation via mist deposition of TiO2/PEDOT・PSS hybrid- and graphene oxide-containing solutions and their characteristics were also studied.
