What are Some Experimental Approaches in Nanotechnology?
Experimental approaches in nanotechnology can be broadly classified into two categories:
Top-down approaches: These methods start with bulk materials and use techniques such as lithography and etching to create nanostructures. For instance, photolithography is widely used in the fabrication of microprocessors and other electronic devices. Bottom-up approaches: These methods build nanostructures atom by atom or molecule by molecule. Techniques such as Chemical Vapor Deposition (CVD) and self-assembly are commonly used. For example, carbon nanotubes can be synthesized using CVD.
