Dr. Carmen Menoni (from Colorado State University), "Exploring the World at the Nanoscale with Bright Beams of Extreme Ultraviolet Light"

Date: 02/17/11
Time: 4-6 p.m.
Audience: Public
Sponsored By: School of Science and Engineering
Location: Coykendall Science Building Auditorium
Contact: Dr. Julio J. Gonzalez, x3724, gonzalj@engr.newpaltz.edu

Detailed photographs taken with powerful optical microscopes have enabled us to visualize intricate phenomena in biological and material systems such as cells, tissue and integrated chips, to name a few. The ability of microscopes to resolve micron-size features relies on using an illumination source emitting in the visible or ultraviolet region of the spectrum. To enable microscopes to 'see' the world of nanostructures, other approaches need to be implemented. This talk will describe new approaches to build optical-microscope similes with superior spatial resolution, capable of resolving features as small as 38 nm. These instruments use novel bright beams of laser light with wavelengths between 10 and 50 nm, in the extreme ultraviolet region of the electromagnetic spectrum. These bright laser beams also enable a number of other nanoscience and nanotechnology applications that will be briefly discussed. Carmen S. Menoni is professor of Electrical and Computer Engineering at Colorado State University. She runs an interdisciplinary research program engaged in the demonstration of unique devices that use bright beams of extreme ultraviolet laser light and optics to probe materials and biological systems at the nanoscale.
