Center for Precision Assembly of Superstratic and Superatomic Solids

The PAS3 led by Columbia University in partnership with City College of New York, studies materials composed of atomically precise low-dimensional building blocks: two-dimensional atomic sheets and zero-dimensional molecular clusters.  The interdisciplinary team comprises faculty from materials science, chemistry, physics, mechanical engineering, and electrical engineering.  The research of the center is strengthened by collaborations with academic and industrial researchers, partnership with Brookhaven National Laboratory, and international partners. Support for the center is provided through the NSF Grant DMR-1420634, part of the NSF MRSEC Program. Additional support is provided by Columbia University.
