このコンテンツについて
Creating nanostructures requires precise methods to control material composition and shape. Two primary approaches exist: top-down and bottom-up. Top-down methods like lithography start with larger materials and carve out nanoscale features. Bottom-up techniques such as self-assembly build structures atom by atom. Each method has distinct advantages depending on the application.This episode explores the tools used in nanofabrication. Photolithography and electron-beam lithography are covered as standard top-down techniques. Self-assembly and atomic layer deposition represent bottom-up strategies. The role of cleanroom environments in minimizing contamination is explained. Nanopatterning methods are discussed as ways to achieve high-resolution structures. The episode provides an overview of how these techniques enable the production of nanomaterials for research and commercial use. Practical considerations such as cost, scalability, and material compatibility are addressed to help students understand the fabrication process.
