News About This Professor


Ph.D., University of Wisconsin—Madison, 1985

Research Interests 

Nanotechnology, surface physics, low energy electron microscopy, photoemission electron microscopy, scanned probe microscopies, templating for directed self-assembly.


Professor Ray Phaneuf joined UMD’s Department of Physics in 1985, where he used electron diffraction to study phase transformations on stepped Si(111) surfaces, resulting in the identification of a thermodynamically driven faceting associated with the formation of the (7x7) reconstruction. In 1989 he visited Ernst Bauer’s group in Clausthal, Germany, using low energy electron microscopy (LEEM) to image this faceting in real time. In 2000 he joined the Department of Materials Science and Engineering, and began studies of directed self-organization during growth and sublimation on semiconductor surfaces, using lithographic patterning. He was a founding member of the UM-MRSEC. In 2006 he was a visiting professor at the National Nanotechnology Laboratory, in Lecce, Italy. He is the founding director of the Interdisciplinary Minor in Nanoscience and Technology at the UMD. He is the author of more than 80 papers in archival journals, and has given over 40 invited talks on his work in the U.S., Europe and Japan. He was named the Laboratory for Physical Sciences Faculty Researcher of the year in 2002. In addition to MSE, he has affiliate positions in Physics and the Department of Electrical and Computer Engineering. His current research is in the fields of directing self-assembly of nanostructures at the mesoscale, plasmonics, and the application of nanotechnology to the conservation of cultural heritage.
