An NNI workshop report examining trends/opportunities in nanoscale science and engineering for electronic, photonic and magnetic technologies, held February 11-13, 2004. Report on one of a series of topical workshops convened during 2003 an 2004 by the Nanoscale Science, Engineering and Technology (NSET) Subcommittee of the National Science and Technology Council’s Committee on Technology. All were part of the NSET Subcommittee’s long-range planning effort for the National Nanotechnology Initiative. Experts at the event were asked to (1) develop long-term, visionary goals within topical areas and (2) identify specific barriers (or “hard problems”) inhibiting “quantum advances” toward those goals. Workshop findings were considered by the NSET Subcommittee in preparation of the 2004 NNI Strategic Plan and for the 2007 update to that plan.
