What are the Common Fabrication Methods in Nanotechnology?
Nanotechnology involves the creation and manipulation of materials at the nanoscale. To achieve this, several fabrication methods are employed:
- Top-Down Approach: This method involves the miniaturization of bulk materials to nanoscale dimensions using techniques like lithography and etching. - Bottom-Up Approach: This involves the assembly of materials from atomic or molecular components. It includes techniques like self-assembly and chemical vapor deposition (CVD).
