Achieving higher density involves several approaches: 1. Nanofabrication Techniques: Methods such as lithography and self-assembly are employed to create dense patterns at the nanoscale. 2. Material Engineering: Using materials such as graphene, carbon nanotubes, and other nanomaterials which have unique properties that allow for high-density configurations. 3. Quantum Dots and Nanocrystals: These can be used to create dense arrays for applications in quantum computing and advanced sensor technologies.
