Workshop #3 at the NSLS Users' Meeting

Grazing Incidence Small Angle Scattering

Location: Bldg. 510, Physics, Lg Seminar Rm

Date: May 17, 2004

Organizers:
Ben Ocko, BNL (ocko@bnl.gov)
Detlef Smilgies, Cornell University (dms79@cornell.edu)

Description: GISAXS is emerging as an important probe of soft matter systems such as polymer thin films as well as semiconductor and other growth-induced nanostructures. GISAXS is sensitive to both the surface morphology and the internal structure of thin films, and provides information both lateral and normal to the surface on length scales extending from 1-100nm. As a result, GISAXS provides an excellent complement to more conventional nanoscale probes such as atomic force microscopy and transmission electron microscopy. Moreover, because of the limited range of scattering angles GISAXS lends itself to in-situ and real-time studies.The aim of the workshop is to survey recent scientific developments and to discuss future prospects.
