What Are the Main Techniques for Nanomaterial Fabrication?
There are several key techniques for fabricating nanomaterials:
1. Top-down Approaches: These involve the reduction of bulk materials to the nanoscale through methods like lithography, etching, and milling. 2. Bottom-up Approaches: These involve the assembly of nanostructures from smaller units, such as atoms or molecules, through techniques like Chemical Vapor Deposition (CVD), sol-gel process, and self-assembly. 3. Hybrid Approaches: These combine both top-down and bottom-up techniques to fabricate complex nanostructures.
