Diffraction could not be sharp anymore and there would be distortion from boundary effects. During recent quantum-well-state experiments, a diffuse scattering from nano scale metallic isands was observed. This scattering could be either from phonon or distortion. This diffuse scatterig will be studied in detail. The distribution and the thermal properties of the diffuse scattering will be invesitigated. equipment+required: Surface Diffractometer and Roper CCD experiment: scattering from metallic nano scale islands foreign+nationals: hazards: cryogenic hazard in the use of liquid nitrogen minimumdays: 4 name: Hawoong Hong new+request: on nonmembers: unacceptable+dates: March 18-22 #REMOTE_HOST: unknown: Server: zrh.uni.aps.anl.gov Address: 164.54.216.36 *** zrh.uni.aps.anl.gov can't find 164.54.216.50: Non-existent host/domain #REMOTE_ADDR: 164.54.216.50 #CONTENT_LENGTH: 877 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
