Sean M. Pursel, graduate student in engineering science and mechanics, will present a paper titled "Prospects for Nanowire Sculptured Thin Film Devices" at the 51st International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication in Denver, Colorado, May 29 - June 1, 2007. The presentation will focus on recent accomplishments and prospects for the future of Sculptured Thin Films (STFs). STFs made of virtually any solid material point toward new vistas of photonic, fluidic and sensor devices. New optical data is shown for TiOx STFs with engineered spectral holes as a liquid and/or vapor sensor. The paper was co-authored with Mark W. Horn, associate professor of engineering science and mechanics.
