Ray Phaneuf’s research includes experimental studies of directed self-assembly and self-organization, nanoparticle enhanced-spectroscopy, surface faceting transitions, surface phase formation in reactive systems, and the use of surface sensitive electron microcopies in characterizing structures and devices at the nanometer scale.

Ray Phaneuf is an Associate Professor in the Materials Science and Engineering Department at the University of Maryland. He received his PhD in Physics at the University of Wisconsin in 1985, where he worked with M.B. Webb’s group using low energy electron diffraction (LEED) to study phase transformations on Ge(111). He then joined the University of Maryland Physics Department and Laboratory for Physical Sciences, where he continued to use LEED, in this case 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 worked with Ernst Bauer’s group in Clausthal, Germany, using low energy electron microscopy (LEEM) to image this faceting in real time. He subsequently designed and built a LEEM at LPS. In 2000 he joined the Materials Science and Engineering Department, and began studies of directed self-organization during growth and sublimation on semiconductor surfaces, using lithographic patterning. He is the author of more than 50 papers, and has given invited talks on his work in the US, Europe and Japan. He was named the LPS Faculty Researcher of the year in 2002. In addition to MSE, he has affiliate positions in Physics and ECE, and was a founding member of the UM-MRSEC. Phaneuf chaired the organization of the Third International Workshop on Nanometer Scale Spectroscopy and Nanostructure which was held at LPS from December 10-14, 2004.
