Nano Patterning
Abstract:
Self-assembly has become a critical implement in the toolbox of nanotechnologists. Scientists and engineers who explore the nano realm posit that the same types of forces that construct a snowflake - the natural attractions and repulsions that prompt molecules to form intricate patterns - can build useful structures - say, medical implants or components in electronic chips. So far much of the work related to self-assembling nanostructures has been nothing more than demonstrations in university laboratories. To go beyond being a scientific curiosity, these nanotech materials and techniques will have to get from benchtop to a $2-billion semiconductor fabrication facility.
