Duffield Hall, named for Cornell Engineering alumnus David Duffield '62 EE, is one of the country's most sophisticated research and teaching facilities for nanoscale science and engineering. It supports research and instruction in electronic and photonic devices, microelectromechanical devices, advanced materials processing, and biotechnology devices. The facility allows the university to bring together many of the various nanotechnology and materials-development groups that previously did their work independently in various parts of the campus. It includes a large atrium that provides a space where faculty and students can interact in a relaxed, attractive environment, particularly during the winter months.
The facility is also home to the Cornell Nanoscale Science and Technology Facility (CNF) in Knight Laboratory, as well as Cornell's Nanobiotechnology Center (NBTC) and portions of the Cornell Center for Materials Research (CCMR).
