This lecture covers the basics of nanostencil lithography, including the principles, techniques, and advancements in the field. It includes an overview of alternative top-down and bottom-up micro/nano fabrication methods, as well as the process of creating guiding patterns and grayscale patterns. The lecture also discusses the fabrication of large-scale substrates for single nanoparticle printing without lithography. Students will work in groups to share knowledge, present mini-reports, and define research topics for mini-projects. The workflow involves literature reading, self-study, group discussions, and project brainstorming.
