Achieving nanoscale structures involves a variety of techniques:
Lithography: This technique uses light to transfer a pattern onto a substrate, creating extremely small structures. Molecular Beam Epitaxy: A method where atoms are deposited onto a substrate in a highly controlled manner. Chemical Vapor Deposition: This involves chemical reactions that produce thin films or nanostructures on a substrate. Mechanical Milling: Physical processes that break materials down into nanoscale particles.
