What are the Methods for Creating Complex Nanostructures?
Several methods are employed to create complex nanostructures, including top-down and bottom-up approaches. Top-down methods involve the reduction of bulk materials to nanoscale dimensions through techniques like lithography and etching. Bottom-up methods, on the other hand, involve the assembly of nanoscale building blocks, such as atoms or molecules, into larger structures through processes like self-assembly and chemical vapor deposition.
